101130-77-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 101130-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,1,3 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 101130-77:
(8*1)+(7*0)+(6*1)+(5*1)+(4*3)+(3*0)+(2*7)+(1*7)=52
52 % 10 = 2
So 101130-77-2 is a valid CAS Registry Number.

Bronsted Acid Catalyzed Cyclization of Inert N-Substituted Pyrroles to Benzo[ f ]pyrrolo[1,2- a ][1,4]diazepines

Gao, Zeng,Qian, Jinlong,Yang, Huameng,Zhang, Jinlong,Jiang, Gaoxi

, p. 930 - 934 (2021/04/27)

Two approaches involving intramolecular and intermolecular cyclization, respectively, have been developed for the direct and practical construction of a series of important benzo[ f ]pyrrolo[1,2- a ][1,4]azepines by using Bronsted acid catalysts. Upon catalysis by TsOH, the intramolecular dehydroxylation/ring closure of 3-hydroxy-2-[2-(1 H -pyrrol-1-yl)benzyl]isoindolin-1-ones provided various racemic benzo[ f ]pyrrolo[1,2- a ][1,4]azepines in high yields. Furthermore, enantioenriched benzo[ f ]pyrrolo[1,2- a ][1,4]azepines were also obtained by chiral phosphoric acid catalyzed intermolecular addition of [2-(1 H -pyrrol-1-yl)phenyl]methanamines to 2-formylbenzoates under mild conditions.

Synthesis of condensed pyrroloindoles via Pd-catalyzed intramolecular C-H bond functionalization of pyrroles

Seung, Jun Hwang,Seung, Hwan Cho,Chang, Sukbok

supporting information; experimental part, p. 16158 - 16159 (2009/05/08)

A new strategy for the synthesis of condensed hetero- or carbocycles such as pyrroloindoles or fluorenes has been developed that involves the Pd-catalyzed cyclization of readily available N-(2-halobenzyl)pyrroles or their phenyl derivatives. The reaction is proposed to proceed via oxidative addition of benzylic halides to Pd(0) followed by base-assisted C-H bond activation. A broad range of condensed cyclic products could be obtained in good to excellent yields under mild conditions. Copyright
