Calculate Digit Verification of CAS Registry Number 1384975-20:
(9*1)+(8*3)+(7*8)+(6*4)+(5*9)+(4*7)+(3*5)+(2*2)+(1*0)=205
205 % 10 = 5

Stereoselective annelation of 3-substituted imidazo[4,5-b]pyridines with cyanoacetylenic alcohols and domino rearrangement of the adducts

Trofimov, Boris A.,Andriyankova, Ludmila V.,Nikitina, Lina P.,Belyaeva, Kseniya V.,Mal'kina, Anastasiya G.,Dyachenko, Oleg A.,Kazheva, Olga N.,Chekhlov, Anatolii N.,Afonin, Andrei V.

, p. 229 - 244 (2012/06/01)

Imidazo[4,5-b]pyridines are readily annelated (45-50 °C, 24-30 h, MeCN) with cyanoacetylenic tertiary -αalcohols to give stereoselectively functionalized 1,3-oxazolo[3,2-a]imidazo[4,5-b]pyridines in 50-88% yields. The adducts undergo a facile stereoselective hydrolytic dominorearrangement to functionalized derivatives of 2,3-diaminopyridines. ARKAT-USA, Inc.
