Dearomatizing disrotatory electrocyclic ring closure of lithiated N-benzoyloxazolidines

, p. 1049 - 1051 (2002)

Loss of aromaticity ensues when N-benzoyl oxazolidines are lithiated and undergo a 6π disrotatory electrocyclization (see scheme). The stereochemistry of the cyclization shows it to be a new example of an electrocyclic ring closure. The cis-tricyclic prod
