A wavelength-orthogonal photocleavable monochromophoric linker was developed that is based on a 3-acetyl-9-ethyl-6-methylcarbazole (AEMC) moiety substituted at both the phenacyl and benzylic positions with different carboxylic acids. The different carboxylic acids were released sequentially upon irradiation with light of λ ≥ 365 nm and λ ≥ 290 nm, respectively.

Modified polystyrenes having both epoxy moieties and tertiary ester linkages, tertiary ether linkages, or carbonate linkages were synthesized. The polymer films containing a photoacid generator were photo-cross-linkable. The cross-linked polymer films bec
PCl3-mediated transesterification and aminolysis of tert-butyl esters via acid chloride formation

A PCl3-mediated conversion of tert-butyl esters into esters and amides in one-pot under air is developed. This novel protocol is highlighted by the synthesis of skeletons of bioactive molecules and gram-scale reactions. Mechanistic studies revealed that this transformation involves the formation of an acid chloride in situ, which is followed by reactions with alcohols or amines to afford the desired products.

A novel, one-step N-dehydrogenation of amides to enamides is reported. This reaction employs the unlikely combination of LiHMDS and triflic anhydride, which serves as both the electrophilic activator and the oxidant, and is characterized by its simple setup and broad substrate scope. The synthetic utility of the formed enamides was readily demonstrated in a range of downstream transformations.
