A simple, efficient and flexible strategy for the syntheses of cladospolides A-C and iso-cladospolide B is reported here. This strategy involves Julia-Kocienski olefination and Yamaguchi macrolactonization as key steps, starting from either d-ribose or suitable tartaric acid esters. Although our initial efforts towards cladospolide A involving a ring closing metathetic approach were not successful, changing the mode of ring closure and the use of Julia-Kocienski olefination for the construction of the key intermediate solved this issue and paved the way for the completion of total syntheses of this class of natural products.

A simple and highly efficient stereoselective total synthesis of cladospolide A, a polyketide natural product, has been achieved. The synthesis involves stereoselective zinc-mediated allylation, pivotal aldol coupling, and ring-closing metathesis. The pivotal aldol coupling is used for the first time for macrolide construction and provides an effective alternative to Yamaguchi macrolactonization. Georg Thieme Verlag Stuttgart · New York.

A simple and efficient total synthesis of (-)-cladospolide A is described here, which involves either olefin cross metathesis or Julia-Kocienski olefination and Yamaguchi macrolactonization as key steps.
A chemoenzymatic total synthesis of the phytotoxic undecenolide (-)-cladospolide A.
Banwell, Martin G,Loong, David T J
, p. 2050 - 2060 (2007/10/03)
An eleven-step synthesis of the title compound (1) from biocatalytically-derived and enantiomerically pure 'building blocks' alcohol (R)-(-)-9 and ester 13 is described. Attempts to construct the twelve-membered lactone ring of cladospolide A in a direct manner by using a ring-closing metathesis (RCM) reaction failed. However, a ten-membered lactone 19, could be constructed by such means and this was then subject to a two-carbon homologation sequence involving, inter alia, Wadsworth-Horner-Emmons and Yamaguchi lactonisation reactions in the closing stages of the synthesis. The impact of substituent stereochemistries and protecting groups on the RCM reaction leading to various ten-membered lactones is also described.

The enantiomerically pure cis-1,2-dihydrocatechol 7, which is obtained by microbial oxidation of chlorobenzene, has been converted, via a sequence of reactions including ring-closing metathesis and Yamaguchi lactonisation steps, into the natural product (-)-cladospolide A (1).
