Total Synthesis of Epothilone B, Epothilone D, and cisand trans-9,10-Dehydroepothilone D [J. Am. Chem. Soc. 2001, 123, 5407-5413]. James D. White,* Rich G. Carter, Kurt F. Sundermann, and Markus Wartmann Page 5412. Structures 51, 52, 53, and 54 in Scheme 11 are incorrect. The configuration of the C12-C13 trisubstituted alkene is (E), not (Z) as drawn in these structures. An undetected isomerization of (Z)-allylic chloride 50 which occurred during its coupling with stannane 47 led to this error. We are grateful to Professor Samuel Danishefsky and Dr. Alexey Rivkin for drawing our attention to this error. JA0251221 10.1021/ja0251221 Published on Web 01/28/2003
