110969-45-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 110969-45-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,9,6 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 110969-45:
(8*1)+(7*1)+(6*0)+(5*9)+(4*6)+(3*9)+(2*4)+(1*5)=124
124 % 10 = 4
So 110969-45-4 is a valid CAS Registry Number.

Preparation of indoles and oxindoles from N-(tert-butoxycarbonyl)-2-alkylanilines

Clark,Muchowski,Fisher,Flippin,Repke,Souchet

, p. 871 - 878 (2007/10/02)

Treatment of dilithiated N-(tert-butoxycarbonyl)anilines 1 with dimethylformamide or carbon dioxide furnishes intermediates 3, 5, that are easily converted to N-(tert-butoxycarbonyl)indoles 4 and oxindoles (indol-2(3H)-ones, 7), respectively. Condensation of dilithiated 1 with N-methoxy-N-methylamides provides ketones 9 which are cyclized upon trifluoroacetic acid treatment to either 2-substituted 1-(tert-butoxycarbonyl)indoles 10 or 2-substituted indoles 11 depending on the reaction time. This general methodology has been applied to efficient synthesis of 1,2-alkyl-bridged indoles 12, 1,3,4,5-tetrahydrobenz[c,d]indole (16), 2a,3,4,5-tetrahydrobenz[c,d]indol-2(1H)-one (18), and 1-(tert-butoxycarbonyl)1H-pyrrolo[2,3-b]pyridine (21).
