Synthesis of α-azido aldehydes Stereoselective access to a protected lincosamine analogue
摘要:
Reaction of ketone 3 with dichloromethyllithium gave 3. unique branched-chain dichloromethyl sugar 7 whose structure was ascertained by X-ray crystallography. Transformation of 7 in seven steps, involving the key-intermediate alpha-azido-aldehyde 9, afforded the protected lincosamine analogue 14. (C) 1997 Elsevier Science Ltd.
