  Enantiomerically pure phosphonate analogues of cis- and trans-4-hydroxyprolines

  摘要：

  All the enantiomers of 0,0-diethyl 4-hydroxypyrrolidinyl-2-phosphonates, phosphonate analogues of cis- and trans-4hydroxyprolines, have been obtained for the first time. The synthetic strategy involved 1,3-dipolar cycloaddition of (R)- and (S)-N-(1-phenylethyl)-C-(diethoxyphosphoryl)nitrones to ally] alcohol and separation of the corresponding 0,0-diethyl 5-(hydroxymethyl)-2-(1-phenylethyl)isoxazolidinyl-3-phosphonates, which were subsequently mesylated and hydrogenated to undergo intramolecular cyclisation. Absolute configurations of the enantiomeric proline phosphonates were established after N- and 0-derivatization with (S)-O-methylmandelic acid employing the Trost model. (c) 2007 Elsevier Ltd.

  日期：——

  All the enantiomers of (1-amino-3-hydroxypropane-1,3-diyl)diphosphonic acid, newly design phosphonate analogues of 4-hydroxyglutamic acids, were obtained. The synthetic strategy involved Abramov reactions of diethyl (R)- and (S)-1-(N-Boc-amino)-3-oxopropylphosphonates with diethyl phosphite, separation of diastereoisomeric [1-(N-Boc-amino)-3-hydroxypropane-1,3-diyl]diphosphonates as O-protected esters
