  描述：

  dimethyl (R,R)-(+)-3-N,N-bis(α-methylbenzyl)-amino-2-oxopropylphosphonate 在 sodium tetrahydroborate 作用下， 以 四氢呋喃 为溶剂， 反应 4.0h， 生成 dimethyl 3-[(R,R)-N,N-bis(α-methylbenzylamino)]-(2R)-hydroxypropylphosphonate 、 dimethyl 3-[(R,R)-N,N-bis(α-methylbenzylamino)]-(2S)-hydroxypropylphosphonate

  名称：

  Highly diastereoselective reduction of β-ketophosphonates bearing homochiral bis(α-methylbenzyl)amine: preparation of both enantiomers of phosphogabob (GABOBP)

  摘要：

  The reduction of dimethyl 3-N,N-di(alpha-methylbenzyl)amino-2-ketophosphonates 9 with catecholborane at -78degreesC in presence of LiClO4, gave gamma-amino-beta-hydroxyphosphonates 10 and 11 in good yield and with excellent diastereoselectivity. This procedure represents an example of highly diastereoselective 1,4-induction. The hydrolysis and hydrogenation of 10 and 11 afforded the (R)- and (S)-gamma-amino-beta-hydroxypropylphosphonic acid (GABOB(P)), respectively. (C) 2004 Elsevier Ltd. All rights reserved.
