1. meso-2,3-Dimethylsuccinic acid is a reagent used in the synthesis of meso-1,4-diiodo-2,3-dimethylbutane and selenoacetal with an erythro-configured CHMe-CHMe fragment.
2. meso-2,3-Dimethylsuccinic acid was used in the synthesis of: meso-1,4-diiodo-2,3-dimethylbutaneselenoacetal with an erythro-configured CHMe-CHMe fragmenterythro-4-acetoxy-2,3-dimethylbutan-1-ol (±)-faranal
Purification Methods
Crystallise the meso-acid from EtOH/ether or EtOH/chloroform.
Check Digit Verification of cas no
The CAS Registry Mumber 608-40-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,0 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 608-40:
(5*6)+(4*0)+(3*8)+(2*4)+(1*0)=62
62 % 10 = 2
So 608-40-2 is a valid CAS Registry Number.

Directed homogeneous hydrogenation of olefins derived from methyl acrylate proceeds with high selectivity.The reactant must possess a polar substituent at a chiral centre situated in the α'-position; this may be -OH, CO2R or NHCOR.The catalyst should be a cationic chelating rhodium biphosphine complex.In all cases high anti-stereoselectivity is observed in the reduced product, and this can be rationalised by a simple and general model.With an optically active catalyst, efficient kinetic resolution occurs, providing a means of access to optically active acrylates.Experimental details of typical hydrogenation reactions are provided.
