Calculate Digit Verification of CAS Registry Number 1309978-19:
(9*1)+(8*3)+(7*0)+(6*9)+(5*9)+(4*7)+(3*8)+(2*1)+(1*9)=195
195 % 10 = 5

One-pot multi-component synthesis of polyhydroquinolines at ambient temperature

Undale,Shaikh,Gaikwad,Pore

scheme or table, p. 511 - 515 (2012/03/08)

An efficient and eco-friendly one-pot synthesis of polyhydroquinolines at ambient temperature from the multi-component reaction of aldehyde, 1,3-diketone, β-keto ester and ammonium acetate in ethanol medium is described. The probable mechanism of transformation is suggested. The features of this procedure are mild reaction conditions, no need of external catalyst, good yields and the operational simplicity at ambient temperature.
