ENANTIOSELECTIVE CATALYTIC INTRAMOLECULAR CYCLOPROPANATION OF ALLYLIC α-DIAZOPROPIONATES OPTIMIZED WITH DIRHODIUM(II) TETRAKIS
Doyle, Michael P.,Zhou, Qi-Lin
, p. 2157 - 2160 (1995)
High enantiocontrol, up to 85percent ee, has been achieved in intramolecular cyclopropanation reactions of representative allylic α-diazapropionates with the catalytic uses of Rh2(4S-MEOX)4.
TRANSESTERIFICATION PROCESS USING MIXED SALT ACETYLACETONATES CATALYSTS

Paragraph 0064; 0065, (2013/04/13)
This invention is directed to a general catalyst of high activity and selectivity for the production of a variety of esters, particularly acrylate and methacrylate-based esters, by a transesterification reaction. This objective is achieved by reaction of an ester of a carboxylic or a carbonic acid, in particular of a saturated or unsaturated, typically, a 3 to 4 carbon atom carboxylic acid; with an alcohol in the presence of a catalyst comprising the combination of a metal 1,3-dicarbonyl complex (pref. Zn or Fe acetylacetonate) and a salt, in particular an inorganic salt, pref. ZnCl2, LiCI, NaCI, NH4CI or Lil. These catalysts are prepared from readily available starting materials within the reaction medium without the need for isolation (in-situ preparation).
ENZYMATIC SYNTHESIS OF (METH)ACRYLIC ESTERS OF HYDROXY-FUNCTIONAL AROMAS
-
Page/Page column 9, (2010/10/03)
A process for preparing (meth)acrylic esters (F) of hydroxy-functional aromas (A), in which at least one hydroxy-functional aroma (A) in the presence of at least one enzyme (E) is esterified with (meth)acrylic acid (S), or transesterified with at least one (meth)acrylic ester (D), the reaction in the case of the transesterification being effected in the absence of solvents.
