A stereoselective synthesis of (R)-(-)-rolipram from L-glutamic acid is described. The key step is a stereoselective Michael addition of an arylcuprate to a modified pyroglutamic derivative which acts as the template to induce the stereoselectivity. Facile manipulation of the enantiomerically pure Michael product afforded the expected therapeutic agent.
报道了从L-谷氨酸立体选择性合成(R)-(-)-罗利普兰的方法。关键步骤是苯基铜酸盐对改性焦谷氨酸衍生物的立体选择性迈克尔加成反应,该改性焦谷氨酸衍生物作为模板诱导立体选择性。对光学纯迈克尔加成产物进行简单操作即得到预期的治疗药物。
