摘要:
Disclosed are a process for preparation of an optically active 7-substituted 3-(2-aminopropyl)indole compound and an intermediate therefor. In the above preparation process, 7-substituted indole is reacted with L- or DL-serine in the presence of a tryptophan-synthesizing enzyme originating in microorganisms to form corresponding 7-substituted L-tryptophan, and it is subjected, if necessary, to reduction, protection, exchange and elimination.
摘要:
Compounds represented by general formula (I) or physiologically acceptable acid addition salts thereof and medicinal compositions containing these compounds as the active ingredient, wherein Ar represents (Ar-1) or (Ar-2); and A represents -Z-N(Q 1 )(Q 2 ), -CO-R 7 or - (CH 2 ) p -CH(R 8 )-COR 9 . Because of exhibiting strong affinity for 5-HT 4 receptor, these compounds are useful as drugs for accelerating the peristalsis or drugs for improving digestive tract functions.
