Bryostatins, synthesis

The alternative method of reduction of such hydroxyketones is the a //-selective Evans intramolecular delivery of nucleophilic hydride through a cyclic transition state. In Janda s bryostatin synthesis, the diol monoester 182, produced by kinetic resolution with an immobilised lipase (chapter 29) is reduced to the an//-diol 183 by acetoxy-borohydride. The hydride delivery is intramolecular through a chair transition state 184. This is 1,3-control via a cyclic transition state (chapter 21).30... [Pg.700]
