Synthetic Modification of 1,3-Thiazolidin-4-One 1,1-Dioxides
摘要:
The reactivity of EWG (electron withdrawing group)-activated methylene group in 1,3-thiazolidin-4-one 1,1-dioxides were investigated. Novel derivatives of 1,3-thiazolidin-4-one 1,1-dioxides were prepared (the heterocyclic core was modified with carboxamide and carboxthioamide moieties as carbonyl group analogues). The products, which have functional groups for possible future modifications, are described and characterized.

A simple ‘three-component-reaction’ between halo- or alkylthio-ketenes, Schiff bases and sulfurdioxide, yielding 4-oxo-1,3-thiazolidine-1,1-dioxides 4 in one step, is presented.
