Abstract: We describe herein an efficient and diastereoselective substrate-directable Heck-Matsuda reaction with nonactivated five-membered olefins. The carbamate acts as the main directing group in the arylation process allowing the synthesis of several functionalized aryl cyclopentenes in good to excellent diastereoselectivities (>85:15) and in isolated yields ranging from 41 to 90%. No double bond isomerizations were observed in these Heck reactions, and the newly created benzylic centers were preserved in all cases examined. The substrate directable Heck arylation approach was successfully applied in a straightforward total synthesis of the sphingosine 1-phosphate receptor-subtype 1 (S1P(1)) agonist VPC01091 by a concise and practical route involving 5 steps in 40% overall yield.
