37505-02-5 Usage

Uses

(R)-(-)-2-Hydroxy-2-methylbutyric Acid is derived from (S)-(-)-1-(1-Naphthyl)ethylamine (N368460), which is used in the asymmetric synthesis of α-cyanocarboxylates. Also used in the synthesis of chiral imadazolin-2-ylidene ligands used in organometallic catalysis. Chiral/Asymmetric synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 37505-02-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,5,0 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 37505-02:
(7*3)+(6*7)+(5*5)+(4*0)+(3*5)+(2*0)+(1*2)=105
105 % 10 = 5
So 37505-02-5 is a valid CAS Registry Number.

Process for preparing optically active α-hydroxy acids and derivatives thereof

-

Page/Page column 19, (2008/06/13)

The present invention provides a process for preparing optically active α-hydroxy acids and derivatives thereof by subjecting the alkylated 1,3-dioxolanones of formula (IV) wherein R1and R2are the same or different and are each independently H or C1-6alkyl; R5is H, C1-16alkyl, or unsubstituted or substituted phenyl; and R6is C1-8alkyl, C2-7alkenyl or unsubstituted or substituted benzyl, to either alcoholysis or hydrolysis, in which the alkylated 1,3-dioxolanones are obtained by using 10-camphorsulfonamide as a chiral auxiliary.

Enzyme-catalyzed synthesis of (R)-ketone-cyanohydrins and their hydrolysis to (R)-α-hydroxy-α-methyl-carboxylic acids

Effenberger,Horsch,Weingart,Ziegler,Kuhner

, p. 2605 - 2608 (2007/10/02)

(R)-Ketone-cyanohydrins (R)-2 are obtained with high enantioselectivity from aliphatic ketones 1 and HCN in organic solvents using (R)-oxynitrilase ( EC 4.1.2.10) as catalyst. Acid catalyzed hydrolysis of the cyanohydrins (R)-2 affords the corresponding (R)-α-hydroxy-α-methyl-carboxylic acids (R)-3 without measurable racemization.
