General Description
2′-Dicyclohexylphosphino-2,4,6-trimethoxybiphenyl, also known as Cy*MeO-BIPHEP, is a chiral ligand widely used in asymmetric catalysis. It is composed of a dicyclohexylphosphino (Cy) group attached to a biphenyl ring with three methoxy (MeO) groups at the 2, 4, and 6 positions. 2′-Dicyclohexylphosphino-2,4,6-trimethoxybiphenyl is known for its ability to efficiently catalyze a variety of asymmetric reactions, including hydrogenation, allylation, and conjugate addition. Its unique steric and electronic properties make it a valuable tool in the development of new synthetic methods and the production of pharmaceuticals and agrochemicals. Additionally, its high stability and solubility in organic solvents make it practical for use in industrial-scale reactions.
Check Digit Verification of cas no
The CAS Registry Mumber 1000171-05-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,0,1,7 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1000171-05:
(9*1)+(8*0)+(7*0)+(6*0)+(5*1)+(4*7)+(3*1)+(2*0)+(1*5)=50
50 % 10 = 0
So 1000171-05-0 is a valid CAS Registry Number.

We have developed a one-iridium-catalyst system that transforms N-allyl-N-sulfonyl-2-(silylalkynyl)aniline derivatives, which are 1,7-enynes in which both multiple bonds have a heteroatom, to the corresponding substituted indole derivatives via isomerizat
