136582-33-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 136582-33-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,5,8 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 136582-33:
(8*1)+(7*3)+(6*6)+(5*5)+(4*8)+(3*2)+(2*3)+(1*3)=137
137 % 10 = 7
So 136582-33-7 is a valid CAS Registry Number.

Synthesis of 3-(arylmethylene)isoindolin-1-ones from ynamides by Heck-Suzuki-Miyaura domino reactions. Application to the synthesis of lennoxamine

Couty, Sylvain,Liegault, Beno?t,Meyer, Christophe,Cossy, Janine

, p. 3882 - 3895 (2006)

Substituted 3-(arylmethylene)isoindolin-1-ones can be efficiently synthesized from various ynamides and boronic acids by palladium-catalyzed Heck-Suzuki-Miyaura domino reactions. This methodology has been applied to the total synthesis of lennoxamine and a concise route to this isoindolobenzazepine alkaloid was achieved in eight steps from 2,3-dimethoxybenzoic acid via a key intermediate ynamide.

Heck - Suzuki - Miyaura domino reactions involving ynamides. An efficient access to 3-(arylmethylene)isoindolinones

Couty, Sylvain,Liegault, Benoit,Meyer, Christophe,Cossy, Janine

, p. 2511 - 2514 (2007/10/03)

(Matrix Presented) Substituted 3-(arylmethylene)isoindolin-1-ones can be efficiently synthesized in a stereoselective manner from various ynamides and boronic acids by palladium-catalyzed Heck-Suzuki-Miyaura domino reactions.
