The first synthesis of pentaprismane, hexacyclo[4.4.0.02,5.03,9.04,8.07,10]decane, is presented with full experimental details. A new and practical synthesis for homopentaprismanone is developed as is methodology for the functionalization of a bridgehead position α to the carbonyl group of this cage compound. The latter uses a mixed acyloin reductive coupling. Favorakii contraction of the bridgehead
给出了五级庚烷的第一合成,即六环[4.4.0.0 2,5 .0 3,9 .0 4,8 .0 7,10 ]癸烷。研发了新的高戊三烯酮合成方法,以及将桥头位置α官能化至该笼状化合物羰基的方法。后者使用混合的酰胆碱还原偶联。桥头官能化的高戊三烯酮的Favorakii收缩被用于进入五the环系统。简要讨论了五pr烷的几何形状,其相对于古巴的行为以及三ane烷化学的未来。
