Attempted N,N-dibenzoylation of aminomethanesulfonic acid results in CS bond cleavage, generating synthetically useful α-benzamidomethylating electrophiles. The importance of this observation in regard to the reported failures to prepare sulfonamide analogs of peptides is discussed.
尝试的氨基甲磺酸的N,N-二苯甲酰化会导致CS键断裂,产生合成上有用的α-苯甲酰胺甲基化亲电试剂。对于所报道的未能制备肽的磺酰胺类似物的失败,讨论了该观察的重要性。
