770-36-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 770-36-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,7 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 770-36:
(5*7)+(4*7)+(3*0)+(2*3)+(1*6)=75
75 % 10 = 5
So 770-36-5 is a valid CAS Registry Number.

Palladium-Catalyzed Tandem Hydrocarbonylative Lactamization and Cycloaddition Reaction for the Construction of Bridged Polycyclic Lactams

Xu, Pengcheng,Qian, Bo,Hu, Bin,Huang, Hanmin

supporting information, p. 147 - 151 (2022/01/04)

The intramolecular hydroaminocarbonylation of alkenes is a compelling tool to rapidly access lactam, a privileged motif ubiquitous in natural products, pharmaceuticals, and agrochemicals. However, selective carbonylation to bridged polycyclic lactams with a lactam nitrogen at a bridgehead position is less explored. We herein report a modular palladium-catalyzed approach to perform a tandem hydrocarbonylative lactamization/Diels-Alder cycloaddition reaction with 2-vinyl aryl aldimines, alkenes, and CO, which offers convenient access to furnish the bridged polycyclic lactams in high yields with high selectivities.

Directed Nickel-Catalyzed Diastereoselective Reductive Difunctionalization of Alkenyl Amines

Zhao, Lei,Meng, Xiao,Zou, Yifeng,Zhao, Junsong,Wang, Lili,Zhang, Lanlan,Wang, Chao

supporting information, p. 8516 - 8521 (2021/10/25)

We report herein an intermolecular syn-arylalkylation and alkenylalkylation of alkenyl amines with two different organohalides (iodides and bromides) using Ni(II) catalyst. The cleavable bidentate quinolinamide is utilized after extensive directing group screening to enable olefin difunctionalization with high levels of regio-, chemo-, and diastereocontrol. This general and practical protocol is compatible with α- or β-substituted terminal alkenes and internal alkenes, providing rapid access to branched aliphatic amines bearing two skipped and vicinal stereocenters with high diastereoselectivities that would otherwise be difficult to synthesize.

Intramolecular N-Me and N-H aminoetherification for the synthesis ofN-unprotected 3-amino-O-heterocycles

Paudyal, Mahesh P.,Wang, Mingliang,Siitonen, Juha H.,Hu, Yimin,Yousufuddin, Muhammed,Shen, Hong C.,Falck, John R.,Kürti, László

supporting information, p. 557 - 560 (2021/02/06)

A mild Rh-catalyzed method for synthesis of cyclic unprotected N-Me and N-H 2,3-aminoethers using an olefin aziridination-aziridine ring-opening domino reaction has been developed. The method is readily applicable to the stereocontrolled synthesis of a va
