专利号:US-7476757-B2 优先权日:2005-02-22 标 题:Process for the synthesis of enantiomeric indanylamine derivatives 发明人:BOULTON LEE TERENCE; LENNON IAN CAMPBELL; BAHAR ELIEZER 权利人:TEVA PHARMA 摘要:A process for manufacturing (R)-propynylaminoindans, and alternatively, a process for manufacturing (S)-propynylaminoindans. The chiral propynylaminoindans include alkoxy or alkylcarbamates derivatives. The process comprises transfer or pressure hydrogenation in the presenc of an optically active catalyst to reduce 1-indanones. The chiral product, either (S)- or (R)-indanols undergo nucleophilic substitution to produce the named product. In an additional aspect, the invention relates to novel intermediates and compounds, namely, substituted indanones, substituted (S)-indanols and substituted (R)-indanols.
