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.
白三烯A酯类化合物可以通过将9-氧代-5,6-顺-环氧-7(E)-烯酸酯与11-三苯基膦酰亚胺-6(Z),9(Z)-二烯反应方便地制备。白三烯A酯类化合物是天然白三烯类化合物的合成中间体,这些化合物已被证明是强效的支气管收缩物质。本文还披露了白三烯A酯类化合物的新型中间体,即9-氧代-5,6-顺-环氧-7(E)-烯酸酯和7-氧代-5,6-顺-环氧庚酸酯。
