In this Letter, we describe an easy and straightforward strategy for the preparation of acyloins (α-hydroxyketones) from Morita–Baylis–Hillman adducts, based on a Curtius rearrangement. Different acyloins were obtained with good overall yield (>40% for three steps). To exemplify the synthetic usefulness of this strategy, total synthesis of (±)-bupropion, a dopamine, and nor-epinefrine reuptake inhibitor
在这封信中,我们描述了一种基于Curtius重排法,从Morita-Baylis-Hillman加合物制备酰基辅酶(α-羟基酮)的简单明了的策略。以良好的总产率(三步> 40%)获得了不同的酰基胞苷。为了举例说明该策略的合成实用性,已通过八个步骤完成了(±)-安非他酮,多巴胺和去甲肾上腺素再摄取抑制剂的全合成,总收率为25%。
