of chiral S(VI) from prochiral S(II) is a formidable challenge due to the inevitable formation of stable chiral S(IV). Previous synthetic strategies rely on the conversion of chiral S(IV) or enantioselectivedesymmetrization of preformed symmetrical S(VI) substrates. Here, we report desymmetrizingenantioselective hydrolysis of in situ-generated symmetric aza-dichlorosulfonium from sulfenamides for
