Stereochemical course of [2+2]cycloaddition of chlorosulfonyl isocyanate to cis and trans 3-O-but-1'-enyl-1,2-O-isopropylidene-α-D-xylofuranose

The asymmetric [2+2]cycloaddition of chlorosulfonyl isocyanate to Z and E 3-O-butyl-1'-enyl-1,2-O-isopropylidene-5-O-trityl-α-D-xylofuranoses proceeds with excellent stereoselectivity affording cis azetidinone 12 from cis olefin and trans azetidine 13 fro
