  Asymmetric synthesis of chiral N-(1-methylbenzyl)aminophosphines

  摘要：

  The reactions of chlorophosphines 1 with (S)- or (R)-1-methylbenzylamines 2 proceed stereoselectively to give N-(1-methylbenzyl)aminophosphines 3, which were isolated as crystalline borane complexes with 100% diastereomeric purity. The absolute configuration of the new chiral compounds was established by X-ray analysis and chemical extrapolation. (C) 2003 Elsevier Science Ltd. All rights reserved.

  A number of N+(alpha-methylbenzyl) phosphorus amides were synthesized, and their stereochemical properties were studied. Reactions of achiral chlorophosphines with optically active alpha-methylbenzylamine are accompanied by asymmetric induction at the phosphorus atom to give optically active diastereoisomers of N-(alpha-methylbenzyl)aminophosphines, which were isolated as the corresponding borane complexes with 100% optical purity. Stereochemically pure (R,S)-aminophosphines were obtained by decomposition of these complexes via treatment with diethylamine. Their oxidation, sulfurization, and alkylation with methyl iodide afforded optically active aminophosphine derivatives. Hydrolysis of (R,S)-aminophosphines gave optically active tert-butylphenylphosphine oxide and phosphonic acid amides. (R,S)- and (S,S)-Diastereoisomers of N-(alpha-methylbenzyl)phosphinic amides were separated by crystallization and flash chromatography, and their absolute configuration was established. Also, derivatives of bis- and tris(alpha-methylbenzylamino)phosphines were synthesized.
