Synthesis of optically active arylglycines by photolysis of optically active (.beta.-hydroxyamino) carbene-chromium(0) complexes
摘要:
Photolysis of [(amino)(aryl)carbene]chromium complexes having the optically active amino alcohol (1R,2S-(-)- or (1S,2R)-(+)-2-amino-1,2-diphenylethanol as the amino group produced aryl-substituted oxazinones in good yield with reasonable diastereoselectivity. Facile separation of diastereoisomers followed by mild reductive cleavage produced several arylglycines, having either electron-donating or withdrawing groups on the aromatic ring, in good overall yield and with excellent enantiomeric excess.
