asymmetric synthesis of nelfinavir is described starting from acrolein and (S)-methyl phenyl sulfoxide. The key features include (a) stereoselective preparation of a β-protected amino-γ,δ-unsaturated sulfoxide by the reaction of an α-sulfinyl carbanion with an unsaturated t-butyl sulfinylimine, (b) stereoselective bromohydrin formation using the pendant sulfoxide group as an intramolecular nucleophile, and
从丙烯醛和(S)-甲基苯基亚砜开始描述了奈非那韦的不对称合成。主要特征包括(a)通过α-亚磺酰基碳负离子与不饱和叔丁基亚磺酰亚胺的反应来立体选择性地制备β-保护的氨基-γ,δ-不饱和亚砜;(b)使用亚砜侧基形成立体选择性溴代醇(c)使用市售或易于制备的廉价原料。
