51632-18-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 51632-18-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,6,3 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 51632-18:
(7*5)+(6*1)+(5*6)+(4*3)+(3*2)+(2*1)+(1*8)=99
99 % 10 = 9
So 51632-18-9 is a valid CAS Registry Number.

Enantioselective Rhodium-Catalyzed Allylic Alkylation of Prochiral α,α-Disubstituted Aldehyde Enolates for the Construction of Acyclic Quaternary Stereogenic Centers

Wright, Timothy B.,Evans, P. Andrew

supporting information, p. 15303 - 15306 (2016/12/09)

A highly enantioselective rhodium-catalyzed allylic alkylation of prochiral α,α-disubstituted aldehyde enolates with allyl benzoate is described. This protocol provides a novel approach for the synthesis of acyclic quaternary carbon stereogenic centers and it represents the first example of the direct enantioselective alkylation of an aldehyde enolate per se. The versatility of the α-quaternary aldehyde products is demonstrated through their conversion to a variety of useful motifs applicable to target-directed synthesis. Finally, mechanistic studies indicate that high levels of asymmetric induction are achieved from a mixture of prochiral (E)- and (Z)-enolates, which provides an exciting development for this type of transformation.

Method for the alkylation of phenylacetonitriles

-

, (2008/06/13)

A method for the alkylation of certain substituted phenylacetonitriles with alkylhalides in the presence of solid particulated alkali metal hydroxides under essentially anhydrous conditions. Trialkylamine catalysts may optionally be utilized. Compounds obtained by this method, some of which are valuable intermediates in the preparation of pyrethroid pesticides, are described.
