专利号:US-6025177-A 优先权日:1998-03-30 标题 :Asymmetric grignard synthesis with cyclic 1,2 aminoalcohols 发明人:SENANAYAKE CHRIS HUGH; BAKALE ROGER P; FANG QUN KEVIN; GROVER PAUL TIMOTHY; HEEFNER DONALD L; ROSSI RICHARD F; WALD STEPHEN ALAN 权利人:SEPRACOR INC 摘要:Processes for preparing a single enantiomer of an alpha , alpha -disubstituted- alpha -hydroxy acetic acid, especially cyclohexylphenylglycolic acid (CHPGA), is disclosed. The processes employ cyclic 1,2-aminoalcohols as chiral auxiliaries by forming diastereomeric esters of aminoalcohols or diastereomeric amides of oxazolidines. Intermediates useful in the process are also disclosed.
