An interesting migration of the rigid structure of benzene was observed when propargylic esters were introduced to the cyclization chemistry of o-alkynyl(oxo)benzene. Various 8-oxabicyclo[3,2,1]octane derivatives with many functional groups could be synthesized from this efficient approach catalyzed by platinum. The high stereo- and regioselectivity involved in this transformation was also attractive
当将炔丙酯引入邻炔基(氧代)苯的环化化学中时,观察到苯的刚性结构发生有趣的迁移。通过这种由铂催化的有效方法,可以合成具有许多官能团的各种 8-氧杂双环 [3,2,1] 辛烷衍生物。这种转化所涉及的高立体选择性和区域选择性也很有吸引力。((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
