An unexpected modulation of the chemoselectivity in the Michael-Dieckmann type reactions of 2-acylaminoacrylates with ketene diethyl acetal is observed, depending on the nature of the acylamino group. Experimental and theoretical studies are presented to offer insights into the origin of this substituent effect in terms of a polar stepwise mechanism.

Page/Page column 2, (2008/12/08)
The present invention relates to a catalytic processes for producing of alkoxycarboxylic acid esters by reaction of hydroxycarboxylic acid and/or its esters with alcohol on a solid acid catalysts at temperatures ranging 100 - 400 °C and pressures 1-100 bar. The method is characterized by that a solid acid catalysts are phosphoric acid and/or its salts of metals I and II groups of Periodical Table on a solid porous material. According to the process alkoxycarboxylic acid esters can be produced in a mild condition and a high yield.
