74262-58-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74262-58-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,6 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74262-58:
(7*7)+(6*4)+(5*2)+(4*6)+(3*2)+(2*5)+(1*8)=131
131 % 10 = 1
So 74262-58-1 is a valid CAS Registry Number.

Metal-catalyzed silylene insertions of allylic ethers: Stereoselective formation of chiral allylic silanes

Bourque, Laura E.,Cleary, Pamela A.,Woerpel

, p. 12602 - 12603 (2008/09/16)

Silylene insertion into allylic ethers occurs suprafacially to provide enantioenriched allylic silanes and disilanes. Silylene insertion to a variety of protected allylic alcohols utilizing silver- and copper-mediated conditions proved to be a general method for allylic silane formation. Allylic disilanes reacted similarly to allylic silanes, undergoing both annulation and allylation reactions. Copyright

Acyclic Stereoselection. 9. Stereochemistry of the Addition of Lithium Enolates to α-Alkoxy Aldehydes

Heathcock, Clayton H.,Young, Steven D.,Hagen, James P.,Pirrung, Michael C.,White, Charles T.,VanDerveer, Don

, p. 3846 - 3856 (2007/10/02)

The stereochemistry of addition of lithium enolates derived from esters and ketones to the α-alkoxy aldehydes 1-5 has been investigated.In all cases, the predominant product is that predicted by application of Felkin's model for asymmetric induction and by assuming the alkoxy group to be the "large" group.The Cram cyclic model for asymmetric induction is not followed.Stereostructures have been assigned by a combination of conversion to products of known stereostructure, 13C and 1H NMR correlations, and single-crystal X-ray analysis.
