(+-)8(9)-EE-14(Z)-E

(+-)14(15)-EE-8(Z)-E (Item No. 10010486) is a potent vasodilator in bovine coronary arteries.{14714,14413} The synthesis of this analog involves the formation of the epoxide at the 14,15-double bond, however, epoxidation can also occur at the 8,9-double bond.{14413} (+-)8(9)-EE-14(Z)-E is a minor product from the synthesis of (+-)14(15)-EE-8(Z)-E. This compound has not been reported in the literature, and its biological activity is not known. It may serve as a tool to verify that the parent compound, (+-)14(15)-EE-8(Z)-E, is pure and does not contain the 8,9-epoxy regioisomer.
