An improved procedure for the synthesis of 4,4-disubstituted-3-oxo-1,2,5-thiadiazolidine 1,1-dioxides
An improved synthesis for the preparation of 3-oxo-1,2,5-thiadiazolidine 1,1-dioxides has been developed. This facile two-step procedure from α-amino acid esters and chlorosulfonyl isocyanate results in excellent yields of products.
