87562-50-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87562-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,6 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87562-50:
(7*8)+(6*7)+(5*5)+(4*6)+(3*2)+(2*5)+(1*0)=163
163 % 10 = 3
So 87562-50-3 is a valid CAS Registry Number.

Base-catalysed asymmetric hydroamination/cyclisation of aminoalkenes utilising a dimeric chiral diamidobinaphthyl dilithium salt

Martinez, Patricia Horrillo,Hultzsch, Kai C.,Hampel, Frank

, p. 2221 - 2223 (2006)

A dimeric proline derived diamidobinaphthyl dilithium salt represents the first example of a chiral main group metal based catalyst for asymmetric hydroamination/cyclisation reactions of aminoalkenes. The Royal Society of Chemistry 2006.

Niobium-Catalyzed Intramolecular Addition of O-H and N-H Bonds to Alkenes: A Tool for Hydrofunctionalization

Ferrand, Laura,Tang, Yue,Aubert, Corinne,Fensterbank, Louis,Mouriès-Mansuy, Virginie,Petit, Marc,Amatore, Muriel

supporting information, p. 2062 - 2065 (2017/04/28)

A convenient, versatile, and easy to handle intramolecular hydrofunctionalization of alkenes (C-O and C-N bonds formation) is reported using a novel niobium-based catalytic system. This atom economic and eco-friendly methodology provides an additional synthetic tool for the straightforward formation of valuable building blocks enabling molecular complexity. Various pyran, furan, pyrrolidine, piperidine, lactone, and lactam derivatives as well as spirocyclic compounds are produced in high yields and selectivities.

Substrate structural effects in yttrium(III)-catalyzed hydroamination/ cyclizations of 1,2-disubstituted and 1,1,2-trisubstituted aminoalkenes terminated by 2-(phenyl) and 2-(2-heteroarenyl) groups

Jiang, Tao,Huynh, Khoi,Livinghouse, Tom

supporting information, p. 193 - 196 (2013/03/13)

A series of 2-phenyl- and 2-(2-heteroarenyl)-bearing amines possessing 1,2-disubstituted and 1,1,2-trisubststuted alkenes have been evaluated in intramolecular hydroaminations catalyzed by Y[N(TMS)(1. Aminoalkenes possessing a terminal 2-(5-trimethylsilyl)thienyl group exhibited substantially enhanced reactivity compared to their 2-(phenyl)-containing counterparts. Cyclization efficiencies imparted by the 2-[(5-trimethylsilyl)furanyl] substituent were comparable or only slightly better than those obtained with the simple the 2-(phenyl) group.
