, p. 2473 - 2478 (2007)
The synthesis of a C1-C14 fragment of a marine cytotoxic natural product Palmerolide A is described. The key steps involved in this synthesis are deoxygenative rearrangement of an alkynol followed by an asymmetric dihydroxylation of a diene ester and CBS-
Claisen rearrangement of γ-hydroxyvinyl sulfones via ketene acetal derivatives. A new entry to functionalized (2E,4E)-alkadienoic esters

In situ prepared ketene acetals of γ-hydroxyvinyl sulfones undergo a Claisen rearrangement affording 3-phenylsulfonyl esters. These compounds are convened to (2E,4E)-dienoic esters by a base-assisted elimination of benzenesulfinic acid.
