Since steric crowding on the endo face of the cis mesylate prevents the mesyloxy group and H(6) from readily achieving the anti relationship necessary for facile E2 elimination, it is not surprising that, in this case, other pathways are found, and a mixture of ene lactams results.
-
A similar mesylation-elimination sequence performed on cis carbinol lib gave ene lactams 13 and 14 in a ratio of 2:1, respectively.
