A useful synthesis of chiral sulfonyl cyanides: (1S,2S,5R)-2-isopropyl-5-methylcyclohexanesulfonyl cyanide
摘要:
A convenient method for the preparation of chiral alkanesulfonyl cyanides, by oxidation of readily available alkyl thiocyanates with m-ClC6H4CO3H, has been developed.

Treatment of racemic binaphthol (1) with neomenthylthioacetic acid chloride (2) gave monoesters 7 and 8. Their separation by column chromatography followed by reduction afforded enantiomerically pure binaphthols.
