Self-immolative polymers degrade by an end-to-end depolymerisation mechanism in response to the cleavage of a stabilizing end-cap from the polymer terminus. Examples include homopolymers, mixed polymers including block copolymers, suitable for a variety of applications. A polyglyoxylate can be end-capped or capped with a linker as in a block copolymer.
used as an aza-Michael donor in organocatalyticasymmetricreactions with symmetric and nonsymmetric unsaturated 1,4-diketones. After hydrolysis (in situ), the N-substituted isatins were obtained in high yields (up to >95%) with high enantioselectivity (up to 95%). Isatin was activated by derivatization to a Schiff base with aniline and used as an aza-Michael donor in organocatalyticasymmetric reactions

leading to good yields, and mechanistic experiments were performed to elucidate the catalyst's possible mechanistic pathway. Moreover, the inherent selectivity challenge regarding α,α-disubstituted aldehydes (decarbonylation problem) was studied and addressed.

and 2 are potential major degradants in over the counter (OTC) products containing phenylephrine HCl and dexbrompheniramine maleate or chlorpheniramine maleate. Compound 2 matches the unknown peak in the solution of stressed active and excipient and thus was identified as the correct degradationproduct. Whether the degradationproduct is racemic or chiral is not known. This article describes synthesis
