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 presence 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.
制造(R)-丙炔基氨基茚和制造(S)-丙炔基氨基茚的过程。手性丙炔基氨基茚包括烷氧基或烷基氨基酸酯衍生物。该过程包括在手性催化剂的存在下进行转移或压力氢化来还原1-茚酮。手性产物,即(S)-或(R)-茚醇经过亲核取代反应产生所述的产品。在另一个方面,本发明涉及新的中间体和化合物,即取代茚酮,取代(S)-茚醇和取代(R)-茚醇。
