✦ Synopsis
The solid phase synthesis of 1,4-benzothiazepin-5-one derivatives, resulting from the reaction of resin-bound protected cysteine with 2-fluoro-5-nitro-benzoic acid followed by a reductive aikylation and an intra molecular cyclization, is described.

The first solid-phase synthesis of 1,4-benzothiazin-3(4H)-ones and 1,4-benzoxazin-3(4H)-ones is reported. Alkylation of the immobilized 4-hydroxy-3-nitrobenzamide 2a and 3-nitro-4-sulfanylbenzamide 2b, followed by reduction and cyclization gave 4. Further alkylation and acylation was performed on th
A series of N-substituted 3,5-bis(substituted-idene)piperidin-4-ones have been prepared using solidphase organic synthesis. The synthesis starts with a Michael addition with piperidin-4-one serving as the donor and REM resin as the acceptor. Various aldehydes were then utilized through a Knoevenagel
