A highly stereoselective and efficient asymmetric total synthesis of (+)-laurencin (1) has been accomplished from the known oxazolidinone 5 in 15 steps. The route features an efficient internal alkylation to form oxocene 3 from 4 and a novel use of acetonitrile anion as a two-carbon acetaldehyde equivalent for direct synthesis of ketone 2 from alpha-alkoxy amide 3.
由已知的恶唑烷酮5分15步完成了(+)-月桂素(1)的高度立体选择性和有效的不对称全合成。该路线的特征是有效的内部烷基化反应,从4形成茂茂化合物3,并新颖地使用乙腈阴离子作为二碳乙醛当量,用于直接从α-烷氧基酰胺3合成酮2。
