  Et3B- and Et2Zn-Mediated Radical Additions to Glyoxylate Imines, Compared Stereoinductions

  摘要：

  1,3-Stereoinduction in the addition of alkyl radicals to glyoxylic imines derived from various chiral amines has been investigated. New synthetic methodologies involving Et3B and Et2Zn as mediators have been compared. Dihydro-1,4-oxazin-2-one (2b) gave the highest d.e. but no chemoselectivity. Open chain analogues derived from beta-alkoxyamines led to good stereoinduction when the reaction was performed with Et2Zn which is a bidentate complexing reagent. (C) 2000 Elsevier Science Ltd.

  Addition of alkyl radicals to the acyclic glyoxylate imine 1 proceeded with a 70 : 30 stereoinduction, even at -78 °C. Addition to the cyclic imine 4b resulted in complete stereocontrol at -40 °C.

  在-78°C下，烷基自由基对非环状乙二醛亚胺1的加成反应形成了70:30的立体诱导产物。而在-40°C时，对环状亚胺4b的加成则实现了完全的立体控制。
