Conjugate addition of nitroalkanes to dimethyl maleate. Regioselective formation of both monoesters of 2-alkylsuccinic acids
Diesters of (E)-2-alkylidenesuccinic acids obtained by conjugate addition of nitroalkanes to dimethyl maleate can be selectively monohydrolyzed at the more reactive carboxyl group to the corresponding half-ester. Alternatively, total hydrolysis to the dia

Asymmetric hydrogenation
The present invention pertains to a process for the preparation of an enantiomerically enriched chiral carboxylic acid derivative having the partial formula: C—C—C—COOX wherein X is a cation, comprising formation of a dehydro precursor salt having the partial formula: C═C—C—COOX by reaction of the corresponding precursor acid with an at least substantially stoichiometric amount of base, and asymmetric hydrogenation of the salt in the presence of a transition metal complex of a chiral phosphine ligand.

Practical access to 2-alkylsuccinates through asymmetric catalytic hydrogenation of Stobbe-derived itaconates
Enantiomerically pure 2-alkylsuccinates are obtained on a 500-g scale after hydrogenation with the cationic rhodium complexes with tetraalkyl-substituted 1,2-bis(phospholanyl)ethane or -benzene ligands [R'-DuPHOS; Eq. (a)]. The catalysts allow smooth hydr
