A modular chem. toolbox was developed for cereblon-directed PROTACs. A variety of linkers was attached to a CRBN ligand via the 4-amino position of pomalidomide. We used linkers of different constitution to modulate physicochem. properties. We equipped one terminus of the linker with a set of functional groups, e.g. protected amines, protected carboxylic acids, alkynes, chloroalkanes, and protected alcs., all of which are considered to be attractive for PROTAC design. We also highlight different opportunities for the expansion of the medicinal chemists’ PROTAC toolbox towards heterobifunctional mols., e.g. with biotin, fluorescent, hydrophobic and peptide tags. This study involved multiple reactions and reactants, such as 1-Bromo-6-chlorohexane (cas: 6294-17-3COA of Formula: C6H12BrCl).

1-Bromo-6-chlorohexane (cas: 6294-17-3) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.COA of Formula: C6H12BrCl

Radioactive iodine isotopes play a pivotal role in radiopharmaceuticals. Large-scale production of multi-patient dose of radioiodinated nuclear medicines requires high concentration of radioiodine. We demonstrate that tetrabutylammonium chloride and methyltrioctylamonium chloride are effective phase transfer reagents to concentrate iodide-124, iodide-125 and iodide-131 from the corresponding com. water solutions The resulting concentrated radioiodide, in the presence of either phase transfer reagent, does not hamper the chem. reactivity of aqueous radioiodide in the copper (II)-mediated one-pot three-component click chem. to produce radioiodinated iodotriazoles.

Wide temperature-range, multi-component, optically isotropic antiferroelectric bent-core liquid crystal mixtures for display applications was written by Wang, Junren;Bergquist, Leah;Hwang, Jung-Im;Kim, Kyeong-Jin;Lee, Joun-Ho;Hegmann, Torsten;Jakli, Antal. And the article was included in Liquid Crystals in 2018.Synthetic Route of C6H5ClO2 The following contents are mentioned in the article:

We present studies on 21 multi-component mixtures consisting of bent-core liquid crystals to obtain room temperature switching between optically isotropic and birefringent states. Four of the mixtures show a significant enhancement over our previous results that were obtained either only at elevated temperatures, or did not show switching at room temperatures with appreciable contrast or speed. Although the switching of the new mixtures still requires high fields and shows only speeds at �00 ms, the results appear already useful for specific applications, such as transparent displays, that do not require video-rate switching and fast refresh rates of the content. This study involved multiple reactions and reactants, such as 4-Chlororesorcinol (cas: 95-88-5Synthetic Route of C6H5ClO2).

4-Chlororesorcinol (cas: 95-88-5) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Synthetic Route of C6H5ClO2
