Practical Sulfonylation of Amines with 4‐Hydroxybenzenesulfonyl Chloride: In Situ Silylation–Desilylation
摘要:
A one-pot procedure for the efficient sulfonylation of amines with 4-hydroxybenzenesulfonyl chloride involving in situ protection and deprotection of the phenol with N,O-bis(trimethylsilyl)acetamide (BTSA) is presented.
