Bu3SnHAIBN is shown to lead to linear and angular six-ring fused polycycles, viz2, 11 and 15 respectively, via consecutive 6-endo-trig modes of cyclisations starting from the corresponding polyolefin acyl radical intermediates.
结果表明,用Bu 3 SnH = AIBN处理适当取代的5,9-二烯,5,9,13-
三烯和5,9,13,17-四烯苯
硒酸酯(例如1a,9和14)会导致线性和线性角六环稠合的多环,即2,11和15分别通过连续6-内从相应的聚烯烃酰基中间体开始环化的-trig模式。
