3-(Hetarylamino)- and 3-[(hetarylmethyl)amino]-isoquinolin-1(2H)-ones
摘要:
The reaction of 2-(cyanomethyl)benzoic acid with amines RNH(2) (R = Ar, Het, CH(2)Ar, CH(2)Het) leads to the formation of the corresponding 3-NHR-isoquinolin-1(2H)-ones. When R = CH(2)Ar and CH(2)Het, there is a side reaction involving hydrolysis of the hydrolytically-unstable intermediates, derivatives of 2-(2-amino-2-iminoethyl) benzoic acid, leading to 2-R-isoquinoline-1,3(2H,4H)-diones.

The alkylation of derivatives of 3-aminoisoquinolin-1(2H)-one in the presence of NaH may proceed in three directions: 1) at the carbonyl group oxygen atom, 2) at the nitrogen atom N-2, and 3) at the 3-amino group. The reaction of equivalent amounts of the reagents gives predominantly products of substitution at the 3-amino group. Repeated alkylation proceeds at the lactam fragment to give a mixture
