asymmetric synthesis of nearly enantiomerically pure (S)-1-aminoindane has been developed. The key step involves the diastereoselective heterogeneous metal-catalyzed reduction of the ketimine of 1-indanone with the chiral auxiliary (R)-phenylglycine amide. The selectivity of the asymmetric hydrogenation step was optimized with regard to metal catalyst, solvent and catalyst loading. The chiral auxiliary was
已经开发了一种实用的不对称合成的近对映体纯的(S)-1-氨基茚满。关键步骤涉及使用手性助剂(R)-苯基甘氨酸酰胺的非对映选择性金属催化的1-茚满酮的酮亚胺还原。关于金属催化剂,溶剂和催化剂负载量,优化了不对称氢化步骤的选择性。通过新型的非还原性方法除去手性助剂。因此,在有效的三步法中,由(R)-苯基甘氨酸酰胺以58%的总收率制备了ee为96%的(S)-1-氨基茚满。
