Preparation of enantiopure sultams by intramolecular Diels–Alder reaction of furan-containing vinylsulfonamides
摘要:
Enantiomerically pure delta- and gamma-sultams have been prepared by intramolecular [4+2] cycloaddition of N-1-phenylethyl substituted vinylsulforiamides with purely thermal activation and under high pressure, An optimized procedure for reductive debenzylation of the resultant delta-sultams is also reported.
