Calculate Digit Verification of CAS Registry Number 205597-71:
(8*2)+(7*0)+(6*5)+(5*5)+(4*9)+(3*7)+(2*7)+(1*1)=143
143 % 10 = 3
So 205597-71-3 is a valid CAS Registry Number.

Palladium catalysed coupling of iodoquinolines and acetylenes - A novel entry to the pyrrolo[3,2,1-ij]-quinoline nucleus

Blurton, Peter,Brickwood, Angela,Dhanak, Dashyant

, p. 2395 - 2403 (2007/10/03)

Treatment of 4-arylamino-8-iodoquinoline derivatives with propargyl alcohol and triethylamine in the presence of iodo(phenyl)bis(triphenylphosphine) palladium and copper(I)iodide gives 6-imino-substituted pyrrolo[3,2,1-ij]quinolines under mild conditions and in moderate yields. Catalytic hydrogenation over Lindlar's catalyst affords functionalised 4H-pyrrolo[3,2,1-ij]quinolines in good yield.
