Stereoselectivetotalsynthesis of decarestrictine-J, a polyketide natural product is described. The synthesis involves the Prins cyclisation and Ring Closing Metathesis (RCM) as key steps.
The first synthesis of (7S,9R)-decarestrictine H and (7R,9R)-decarestrictine H as well as the improved synthesis of decarestrictine J were achieved. The overall yields of (7S,9R)-decarestrictines H and J were 20.9% each in nine to ten steps from (R)-Roche ester using a unified synthetic route via esterification with 3,3-ethylenedioxyhex-5-enoic acid and ring-closing metathesis, which were the key steps
In this communication, a concise and efficient synthetic route for the synthesis of decarestrictine J in enantioselective way has been described. In this synthesis, Yamaguchi esterification and ring closing metathesis (RCM) for macrocyclic ring formation have been applied as key steps.

AbstractStereoselective totalsynthesis of decarestrictine J has been accomplished from inexpensive and commercially available starting materials. This concise synthesis utilizes Jacobsen’s hydrolytic kinetic resolution, regioselective ring opening of epoxide, and Yamaguchi macrolactonisation as key steps. Graphical abstract
An efficient total synthesis of decarestrictine J has been achieved using ring-closing metathesis and Yamaguchi esterification as key steps. The stereogenic centres were generated by means of iterative hydrolytic kinetic resolution (HKR) of racemic epoxides. (c) 2009 Elsevier Ltd. All rights reserved.
