Progress towards the total synthesis of callipeltin A. Asymmetric synthesis of (2 R ,3 R ,4 S )-3-hydroxy-2,4,6-trimethylheptanoic acid
摘要:
A silyl derivative of (2R,3R,4S)-3-hydroxy-2,4,6-trimethylheptanoic acid, a moiety present in the cyclic depsipeptide callipeltin A, was successfully synthesized from L-valine in nine steps using the Heathcock variant of the Evans aldol reaction. (C) 2002 Published by Elsevier Science Ltd.
