Asymmetric synthesis of novel β-substituted β-methoxyacrylates bearing a chiral 1,2-cis-disubstituted cyclopropane substructure
Hasegawa, Daiju,Uchiro, Hiromi,Kobayashi, Susumu
, p. 7185 - 7187 (2002)
The first asymmetric synthesis of β-substituted β-methoxyacrylate bearing a chiral 1,2-cis-disubstituted cyclopropane ring as a 'conformationally locked' substructure, by Claisen condensation and E-selective Wittig reaction was successfully achieved.
Preparations of Bicyclic Chiral Lactone Synthons via Stereospecific Pig Liver Esterase-catalysed Hydrolyses of meso-Diesters. Ring-size induced Reversal of Stereospecificity
Sabbioni, Gabriele,Shea, Marion L.,Jones, J. Bryan
, p. 236 - 238 (1984)
Stereospecific pig liver esterase-catalysed hydrolysis of monocyclic meso-1,2-diesters provides a convenient preparative route to both enantiomers of useful chiral lactones and demonstrates a sharply defined and unprecedented ring-size-mediated reversal of stereospecificity.

Craig, Ryan,Litvajova, Mili,Cronin, Sarah A.,Connon, Stephen J.
supporting information, p. 10108 - 10111 (2018/09/18)
The asymmetric nucleophilic catalysis by fluoride ions at a carbon-based electrophile has been demonstrated for the first time. Using a library of ad hoc designed bifunctional phase-transfer catalysts in which both the anion and the cation are directly involved in the reaction, the desymmetrisation of meso-succinic and -glutaric anhydrides is possible.19F NMR spectroscopic studies support the intermediacy of an acyl fluoride intermediate.

A new structural motif for bifunctional bronsted acid/base organocatalysis
Wakchaure, Vijay N.,List, Benjamin
supporting information; experimental part, p. 4136 - 4139 (2010/08/07)
"Chemical equation presented" Naturally synthetic: Acid/base catalyst (S)-I can be used in highly enantioselective alcoholytic desymmetrizations of meso anhydrides. For example, the methanolysis of cyclobutane anhydride deriva-tive 2 gave hemiester 3 in 99:1 e.r. (see scheme). Ester 3 was used in a short enantioselective synthesis of (+ )-grandisol.
