Norris, Peter published the artcileDevelopment of reactions of 6- and 5-substituted 1,3-dimethyluracils with dimethylsulfoxonium methylide, Application In Synthesis of 5034-06-0, the publication is Journal of Organic Chemistry (1999), 64(20), 7290-7298, database is CAplus.

6-Chloro-1,3-dimethyluracil reacts with dimethylsulfoxonium methylide, MeS(:O):CH₂, to give sulfoxonium ylide I in 51% yield. The structure of I was established spectroscopically and by its reactions with various electrophiles and electron-deficient olefins. Thus, I is converted by HCl to a sulfoxonium chloride which then yields 6-(chloromethyl)-1,3-dimethyluracil (II) by heating in MeCN. I undergoes deuterium exchange at the 5-position, at its methine carbon, and into its Me groups attached to sulfur. Reaction of I with BzCl gives the highly substituted ylide III or the nucleophilic substitution products II and (α-chlorophenacyl)uracil IV, depending on reaction conditions. Treatment of I with electron-deficient olefins yields 6-cyclopropyluracils, e.g. V. Many of the cyclopropyluracils were converted to trans-1-(1,3-dimethyluracilyl)-2-vinylcyclopropanes and cycloheptenyluracils. Reaction 5-(phenylsulfinyl)-1,3-dimethyluracil with MeS(:O):CH₂ yields cyclothymine VI, whereas reaction of 5-phenylseleninyl-1,3-dimethyluracil with MeS(:O):CH₂ gave I as the major product.

Laha, Joydev K. published the artcileDesign, Sustainable Synthesis, and Programmed Reactions of Templated N-Heteroaryl-Fused Vinyl Sultams, Recommanded Product: ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride, the publication is Journal of Organic Chemistry (2017), 82(18), 9350-9359, database is CAplus and MEDLINE.

A de novo design and synthesis of N-heteroaryl-fused vinyl sultams as templates for programming chem. reactions on vinyl sultam periphery or (hetero)aryl ring is described. The key features include rational designing and sustainable synthesis of the template, customized reactions of vinyl sultams at C=C bond or involving N-S bond cleavage, and reactions on the periphery of the heteroaryl ring for late-stage diversification. The simple, easy access to the template coupled with opportunities for the synthesis of diversely functionalized heterocyles from a single template constitutes a rare study in contemporary organic synthesis.

Shankar, Ravi published the artcileCatalytic oxidation of diorganosilanes to 1,1,3,3-tetraorganodisiloxanes with gold nanoparticle assembly at the water-chloroform interface, Recommanded Product: Dichloro(hexyl)(methyl)silane, the publication is New Journal of Chemistry (2019), 43(2), 813-819, database is CAplus.

The formation of the spherical self-assembly of gold nanoparticles (AuNPs) of 200 ± 20 nm size at the water-chloroform interface is achieved by employing the cyclotetrasiloxane [RSCH₂CH₂SiMeO]₄ (R = CH₂CH₂OH) as the stabilizing ligand. The interfacially stabilized AuNPs act as a versatile catalyst for selective hydrolytic oxidation of only one of the Si-H bonds in secondary organosilanes, RR¹SiH₂ (R, R¹ = alkyl, aryl, and sila-alkyl), to afford the high yield synthesis of 1,1,3,3-tetraorganodisiloxanes, (HRR¹Si)₂O.

Bryant, Laura A. published the artcileEnantioselective Organocatalytic Synthesis of Bicyclic Resorcinols via an Intramolecular Friedel-Crafts-Type 1,4-Addition: Access to Cannabidiol Analogues, Category: chlorides-buliding-blocks, the publication is Advanced Synthesis & Catalysis (2021), 363(16), 4067-4074, database is CAplus and MEDLINE.

A highly enantioselective, organocatalytic intramol. cyclization by a Friedel-Crafts-type 1,4-addition using a Joergensen-Hayashi-like organocatalyst with a large silyl protecting group and showed that heat improved the reaction yield with virtually no detriment to enantioselectivity. A variety of bicyclic resorcinols were obtained with excellent enantioselectivities (up to 94%). To show the utility of these constructs, and as part of a wider project involved the synthesis of cannabinoid-like compounds, the resorcinol formed was used to generate both ‘normal’ and ‘abnormal’ cannabidiol which had anticonvulsant activity.
