An improved synthesis for the preparation of 3-oxo-1,2,5-thiadiazolidine 1,1-dioxides has been developed. This facile two-step procedure fromα-amino acid esters and chlorosulfonyl isocyanate results in excellent yields of products.
已经开发了用于制备3-氧代-1,2,5-噻二唑烷1,1-二氧化物的改进的合成方法。由α-氨基酸酯和氯磺酰基异氰酸酯组成的这种简便的两步过程可实现极好的产品收率。
