Methanesulfonamides were deprotected to their parent amines via deprotonation and oxygenation with O2 (g), even in the presence of other traditional sulfonamides.
甲烷磺酰胺即使在其他传统的磺酰胺存在下,也能通过去质子化和用O 2(g)氧化而脱保护为其母体胺。

The reaction of different protected alcohols, amines and amides with lithium and a catalytic amount of naphthalene (4 mol %) in THF at low temperature leads to their deprotection under very mild reaction conditions, the process being in many cases chemoselective. (C) 1997 Elsevier Science Ltd.
