AB and ABA block copolymers of poly(ethylene glycol-b-methylene) and poly(dimethylsiloxane-b-methylene) were prepared by hydroboration polyhomologation protocol. Control over the chain length of the polymethylene block was achieved by adjusting the initial molar ratio of ylide to organoborane. ABA block copolymers of polymethylene-polydimethylsiloxane-polymethylene were synthesized by a similar approach using thexyl borane as the difunctional hydroboration agent.

Mishra, Anu published the artcileVisible light triggered, catalyst free approach for the synthesis of thiazoles and imidazo[2,1-b]thiazoles in EtOH : H₂O green medium, Related Products of chlorides-buliding-blocks, the publication is RSC Advances (2016), 6(54), 49164-49172, database is CAplus.

The development of a visible light promoted, mild and greener approach for the synthesis of highly functionalized thiazoles and imidazo[2,1-b]thiazoles under photochem. activation in EtOH : H₂O green medium was demonstrated. The characteristic feature of the present protocol was the utilization of visible light (an omnipresent, nontoxic, environmentally benign and inexpensive reagent) to form C-S and C-N bonds and circumvent the use of catalysts or photosensitizers. The reported protocol was the first example of visible light promoted synthesis of thiazoles and imidazo[2,1-b]thiazoles with various attractive features like being catalyst free, eco-efficient and possessing cost effectiveness, short reaction time, excellent yields and sustainability to fulfill the parameters of green chem.

Parvathy, Kattera S. published the artcileUltrasound-assisted reaction of 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl bromide with potassium salt of curcumin under PTC conditions, Application In Synthesis of 23616-79-7, the publication is Ultrasonics Sonochemistry (2008), 15(4), 571-577, database is CAplus and MEDLINE.

Reaction of 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl bromide with potassium salt of curcumin [bis-1,7-(3′-methoxy-4′-hydroxy)phenyl-5-hydroxy-1,4,6-heptatrien-3-one] under either thermal or high pressure conditions affect the labile substrate, curcumin, thus resulting in drastic reduction in the yields of the glucosides. This drawback could be effectively overcome by carrying out the biphasic reaction in the presence of a phase transfer catalyst under the effect of ultrasound. The reaction under the sonochem. conditions was faster and resulted in the increased yield of the glucoside products. The reaction was investigated in detail with a view to optimizing the yield of the glucosides. The detailed study clearly indicated the important role of the nature and quantity of the phase transfer catalyst employed in the reaction. Also, the selectivity with respect to the formation of mono- or di-β-glucosides under both mono- and biphasic reaction conditions was clearly discernable. The study establishes a simple synthetic protocol for the glucoside derivatives of curcumin in high yields and selectivity using ultrasonic waves.

Kavitha, Kotthireddy published the artcileAn unusual synthesis of 3-(2-(arylamino)thiazol-4-yl)-2H-chromen-2-ones from ethyl 2-(chloromethyl)-2-hydroxy-2H-chromene-3-carboxylate via benzopyran ring opening, HPLC of Formula: 3696-23-9, the publication is Molecular Diversity (2019), 23(2), 443-452, database is CAplus and MEDLINE.

An unusual and unexpected synthesis of 3-(2-(arylamino)thiazol-4-yl)-2H-chromen-2-ones was observed by the reaction of Et 2-(chloromethyl)-2-hydroxy-2H-chromene-3-carboxylate with various arylthioureas in ethanol under mild reaction conditions with excellent yields. The ambiguity in the structure of the obtained products was solved by recording its single-crystal X-ray anal. This protocol was found to be a novel approach for the preparation of title compounds via benzopyran ring opening. A systematic plausible mechanism was proposed for the formation of the product. Also, an efficient one-pot three-component method was demonstrated for the formation of title compounds starting from salicylaldehyde.

Kavitha, K. published the artcileAn expedient one-pot tandem method for the synthesis of 3-(2-(phenylamino)thiazol-4-yl)-2H-chromen-2-ones under green conditions, Name: 1-(4-Chlorophenyl)thiourea, the publication is Journal of the Iranian Chemical Society (2019), 16(9), 1913-1921, database is CAplus.

This paper describes a facile pathway for the one-pot three-component synthesis of 3-(2-(phenylamino)thiazol-4-yl)-2H-chromen-2-ones starting from ethyl-4-chloroacetoacetate by treating it with equimolar amounts of various phenylthioureas and salicylaldehyde. Use of biosynthetically prepared L-proline as an efficient catalyst and naturally extracted renewable polyethylene glycol-600 (PEG-600) as an effective green reaction media are the added advantages of this method. Alternatively, tandem, stepwise methods have been proposed to isolate the intermediate and to study the possible reaction mechanism. These reactions are very simple, rapid, cost effective, industrially viable, which would be applied for various biomass conversions.

Salvino, Joseph M. published the artcileNovel small molecule guanidine Sigma1 inhibitors for advanced prostate cancer, Related Products of chlorides-buliding-blocks, the publication is Bioorganic & Medicinal Chemistry Letters (2017), 27(10), 2216-2220, database is CAplus and MEDLINE.

Prostate cancer is the most frequently diagnosed malignancy and the leading cause of cancer related death in men. First line therapy for disseminated disease relies on androgen deprivation, leveraging the addiction of these tumors on androgens for both growth and survival. Treatment typically involves antagonizing the androgen receptor (AR) or blocking the synthesis of androgens. Recurrence is common and within 2-3 years patients develop castration resistant tumors that become unresponsive to AR-axis targeted therapies. To provide a more effective treatment, the authors are utilizing an approach that targets a key scaffolding protein, Sigma1 (also known as sigma-1 receptor), a unique 26-kDa integral membrane protein that is critical in stabilizing the AR. Herein the authors report on a new series of Sigma1 compounds for lead optimization derived from a hybrid pharmacophore approach.

Ramesh, Perla published the artcileRecyclable Aliphatic Nitrile-Template Enabled Remote meta-C-H Functionalization at Room Temperature, Synthetic Route of 51656-68-9, the publication is Journal of Organic Chemistry, database is CAplus and MEDLINE.

This article describes the development of a new aliphatic nitrile-template-directed remote meta-selective C-H olefin functionalization reaction of arenes. Remarkably, unlike the previous reports, this process was feasible at room temperature and enabled the formation of products with excellent regio-selectivity. The present protocol encompasses a broad spectrum of substituted dihydrocinnamic acids and olefins, producing meta-C-H olefinated products (up to 96% yield). In addition, the efficacy of the present method was showcased by the synthesis of various drug analogs (e.g., cholesterol, estrone, ibuprofen, and naproxen). Significantly, the robustness of meta-olefination was also demonstrated by gram-scale synthesis. The new nitrile-based meta-directing template, in particular, could be easily synthesized in two steps and recycled under mild conditions. A, B, and C represent the Intrinsic Reaction Curves (IRCs) for the meta-C-H activation, Alkene Insertion, and β-Hydride elimination, resp., along with the corresponding transition states. CYL view software was used for showing transition state structures.
