: 15 : 16 = 4 : 1 : 1. The major anti-alcohol 14 was taken through to the methoxyacetal 27 so confirming this strategy for the stereoselectivesynthesis of the C(17)–C(23) fragment of bryostatins. The diol 30, which has configurations at each of its three chiral centres corresponding to the C(23)–C(27) fragment of bryostatins, was prepared in two steps from the aldehyde 28 and converted into the vinylstannane
