标 题:Chiral and achiral synthesis of 2-acyl substituted chromanes and their derivatives
发明人：KANTER JAMES; MARLOWE CHARLES; PANDEY ANJALI; MULLINS JOHN J G; SCARBOROUGH ROBERT; BUTKE GREG; JACOBSON BARRY; WALKER DEREK
摘要:Disclosed are processes for producing a (2S) or (2R) 4-oxo-chroman-2-yl acyl compounds and chroman-2-yl acyl compounds, esters or amides thereof as well as derivatives thereof. Such processes may involve chiral synthesis or achiral synthesis, preferably coupled with a resolution procedure. Such compounds, particularly (2S) or (2R) acetic acid esters, are useful intermedates for producing platelet aggregation inhibitors and/or are themselves potent platelet aggregation inhibitors. Further disclosed are processes for making derivatives of such substantially pure, or enhanced compositions of single (2R) or (2S) enantiomer intermediates or processes for producing final products or salts from such desired enantiomers.
