Popis:	Loss of aromaticity ensues when N-benzoyl oxazolidines are lithiated and undergo a 6.pi. disrotatory electrocyclization. The stereochem. of the cyclization shows it to be a new example of an electrocyclic ring closure. The cis-tricyclic products epimerize to their more stable trans diastereoisomers in aq. acid.
