Total synthesis of (±)-diplodialide-A
Abstract
The total synthesis of a ten-membered lactone, diplodialide-A (1)[(E)-3-oxodec-4-en-9-olide], is described, involving the lactonization of the seco-acid derivative (22a) and the γ-selenenylation of the dianion of the β-keto lactone (24), followed by selenoxide elimination.
