The products from, and the effect of solvent on the ring-opening of 15α,16-epoxyphyllocladane (1) and of 16,17-epoxyphyllocladane (17) with boron trifluoride have been examined. The action of other Lewis acids has also been investigated. Treatment of 15α,16-epoxykaurane (21) with boron trifluoride–ether complex results in rearrangement, giving atisiran-15-one (25).
考察了溶剂与三氟化硼对15α,16-环氧叶环烷(1)和16,17-环氧叶环烷(17)的开环作用以及溶剂的影响。还研究了其他路易斯酸的作用。用三氟化硼-醚配合物处理15α,16-环氧天金烷(21)会导致重排,产生atisiran-15-一(25)。
