Allylic oxidation of 4-allyl-1-dimethyl-t-butylsilylazetidin-2-ones (5,7) gave the 4-(1-hydroxyprop-2-ene-1-yl) derivatives (6,8).Radical benzoyloxylation of the silylated 8-oxo-7-azabicyclo<4.2.0>oct-3-ene (18) provided four allylic monobenzoates.Progression of (8) and (29) afforded, respectively, 4-acyloxy olivanic acid analogues containing trans- (16) and cis- (31) substituents at C-6.
