Vinyl bisphosphonates can be readily prepared by condensation of an aromatic aldehyde with the tetraester of a methylenebisphosphonate, and reduction of the resulting olefin is an attractive strategy for the preparation of monoalkyl geminal bisphosphonates. Conjugate reduction through use of variations on the Stryker approach has proven to be an efficient method for that reduction, even in the presence
乙烯基二膦酸酯可以通过芳族醛与亚甲基二膦酸酯的四酯的缩合容易地制备,并且所得烯烃的还原是制备单烷基偕二膦酸酯的有吸引力的策略。通过使用 Stryker 方法的变体进行共轭还原已被证明是一种有效的还原方法,即使存在也可以还原的芳香族取代基。此外,类异戊二烯链中的远程烯烃在这种缀合物还原中不受影响,从而可以得到感兴趣的类异戊二烯取代的三唑二膦酸盐作为萜类生物合成的潜在抑制剂。
