Abstract
CHEMISTRY OF 4-0XO-THIAZOLIDINES
4-oxo-thiazolidines ( 2) are derivatives of thiazolidine
(1) with a carbonyl group at position-4.

The substituents in the 4-oxo-thiazolidine ring in the 2,3
and 5-positions may be varied to give different derivatives,
but the greatest difference in structure and properties is exerted
by the group attached to the carbon atom in the 2-
position, to give 2,4- dioxo-thiazolidine (3), 2-thioxo-4-oxothiazolidine
(4), and 2-imino-4-oxo-thiazolidine (5), ring sys-
