Calculate Digit Verification of CAS Registry Number 75292-98:
(7*7)+(6*5)+(5*2)+(4*9)+(3*2)+(2*9)+(1*8)=157
157 % 10 = 7
So 75292-98-7 is a valid CAS Registry Number.

Synthesis of 2-amino-4-(2-benzofuryl)Δ1 pyrrolines and study of their antidysrhythmic properties

Maillard,Langlois,Vo Van,et al.

, p. 353 - 358 (2007/10/02)

The synthesis of 2-amino 4(2-benzofuryl)Δ1 pyrrolines, substituted in the aromatic ring and/or on the nitrogen atom of the amino group, is described. These derivatives are obtained from 3 (2-benzofuryl) acrylic esters, on which nitromethane is added. The reduction of 4-nitrobutyric esters lead to pyrrolidinones, and then to the entitled derivatives. Some analogs, the benzofuran ring of which is replaced by another heterocycle, were also prepared. Some of them exhibit interesting antidysrhythmic properties.
