ABSTRACT:
Esters of leukotriene A are conveniently prepared by reacting 9-oxo-5,6-trans-epoxynon-7(E)-enoates with 11-triphenylphosphoranylidene undec-6(Z),9(Z)-diene. Esters of leukotriene-A are useful intermediates in the synthesis of naturally occurring leukotrienes, which have been shown to be potent broncho-constricting substances. Novel intermediates to the esters of leukotriene A, 9-oxo-5,6-transepoxynon-7(E)-enoates and 7-oxo-5,6-transepoxyheptanoates, are disclosed.
