Calculate Digit Verification of CAS Registry Number 1603163-34:
(9*1)+(8*6)+(7*0)+(6*3)+(5*1)+(4*6)+(3*3)+(2*3)+(1*4)=123
123 % 10 = 3

Catalyst-free concise synthesis of imidazo[1,2-a]pyrrolo[3,4-e]pyridine derivatives

Chen, Xuebing,Zhu, Li,Fang, Li,Yan, Shengjiao,Lin, Jun

, p. 9926 - 9934 (2014/03/21)

An eco-benign and highly efficient aza-ene reaction for preparing imidazo[1,2-a]pyrrolo[3,4-e]pyridine derivatives from heterocyclic ketene aminals (HKAs) and 2,3-dioxopyrrolidines has been developed in environmentally benign solvent systems, as well as in the absence of any catalyst. The procedures feature excellent yields, short reaction times, a convenient one-pot method, and simple purification that not only minimise the generation of waste but also simplify the work-up procedure.
