90865-70-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90865-70-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,6 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90865-70:
(7*9)+(6*0)+(5*8)+(4*6)+(3*5)+(2*7)+(1*0)=156
156 % 10 = 6
So 90865-70-6 is a valid CAS Registry Number.

Synthesis of optically active β- Or γ-alkyl-substituted alcohols through copper-catalyzed asymmetric allylic alkylation with organolithium reagents

Guduguntla, Sureshbabu,Fananas-Mastral, Martin,Feringa, Ben L.

, p. 8274 - 8280 (2013/09/24)

An efficient one-pot synthesis of optically active β-alkyl-substituted alcohols through a tandem copper-catalyzed asymmetric allylic alkylation (AAA) with organolithium reagents and reductive ozonolysis is presented. Furthermore, hydroboration-oxidation following the Cu-catalyzed AAA leads to the corresponding homochiral γ-alkyl-substituted alcohols.

Hydride reduction of alpha, beta-unsaturated carbonyl compounds using chiral organic catalysts

-

Page/Page column 20-21, (2008/06/13)

Nonmetallic, chiral organic catalysts are used to catalyze the 1,4-hydride reduction of an α,β-unsaturated carbonyl compound. The α,β-unsaturated carbonyl compound may be an aldehyde or cyclic ketone, and the hydride donor may be a dihydropyridine. The reaction is enantioselective, and proceeds with a variety of hydride donors, catalysts, and substrates. The invention also provides compositions effective in carrying out the 1,4-hydride addition of α,β-unsaturated carbonyl compounds.
