Calculate Digit Verification of CAS Registry Number 1649449-59:
(9*1)+(8*6)+(7*4)+(6*9)+(5*4)+(4*4)+(3*9)+(2*5)+(1*9)=221

Application of privileged molecular framework of 7-fluoro-1,4- benzodiazepin-2-one-5-methylcarboxylate to the synthesis of its 1- and 5-disubstituted analogs of medicinal interest

Devi, Pragati,Gupta, Aarti,Kishore, Dharma

, p. 991 - 998 (2014)

Synthetic potential of the privileged molecular framework of 7-fluoro-1,4-benzodiazepin-2-one containing a methyl carboxylate substituent at its 5-position was exploited to develop efficient protocols to the synthesis of several novel 5-(1′,3′,4′)oxadiazole ring incorporated analogs of medicinal interest, appended with the Mannich's base motifs at the nitrogen atom in its seven-membered ring.
