D. Schinzer et al., STUDIES TOWARDS THE TOTAL SYNTHESIS OF EPOTHILONES - ASYMMETRIC-SYNTHESIS OF THE KEY FRAGMENTS, Chemistry, 2(11), 1996, pp. 1477-1482
Members of a new class of macrolide-the so-called epothilones (1)-show
ing a taxol-like biological activity have recently been isolated. A co
nvergent approach to 1 is presented, and the asymmetric syntheses of t
he three key intermediates 3, 4, and 8 are reported.
