carboxylic acid fragment of jamaicamide C contains a methyl stereocenter and a trisubstituted E chloroolefin. Herein, we present the nonracemic synthesis of the aliphatic chain of jamaicamide C. The methyl stereocenter was installed using Evans’ oxazolidinone methodology, and the trisubstituted chloroolefin was set by silylstannylation of a triple bond.
