Intramolecular radical cyclisations involving α-acetal methyl centres, and 2(5)-furanone and maleate electrophores, allow the facile synthesis of spiro- and linear-fused γ-lactone ring systems (5), (6), (7) and (8) present in the ‘ginkgolides’ viz (1) and (2) produced by the ginkgo tree .
涉及α-缩醛甲基中心,2(5 )-呋喃酮和马来酸酯电泳的分子内自由基环化反应可轻松合成螺旋和线性稠合的γ-内酯环系统(5),(6),(7)和( 8)存在于由银杏树产生的“银杏内酯”即(1)和(2)中。
