epoxides have been obtained from well defined hydroxy-alkenyl derivatives. Their subsequent intramolecular ring-opening allowed unprecedented classes of spiro-lactams to be obtained. The effect of the epoxide stereochemistry and of the reaction temperature on the regioselective formation of five- or four-membered ring spiro derivatives was explored. This transformation is part of a program directed towards
已经从明确定义的羟基-烯基衍生物中获得了多种羟基环氧化物。他们随后的分子内开环允许获得前所未有的螺内酰胺类。探讨了环氧化物立体化学和反应温度对五元或四元环螺衍生物的区域选择性形成的影响。这种转化是旨在合成多功能化 β-内酰胺作为胆固醇吸收抑制剂 (CAIs) 的计划的一部分。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
