Synthesis and antimicrobial activity of some 4-thiazolidinones
Trivedi, G. S.,Desai, N. C.
, p. 366 - 369 (2007/10/02)
4-Thiazolidinones have been prepared by the reaction of mercaptoacetic acids with anils or with aldehydes and amines.The structures of some of the 4-thiazolidinones (III-V) have been established on the basis of their elemental analyses and spectral data.T
