El-Ghandour, Nagui published the artcilePreferential manner of the cycloaddition of diazomethane to some methyl ¦Â-acylacrylates, Application of 2-Methylene-4-oxo-4-phenylbutanoic acid, the publication is Bulletin de la Societe Chimique de France (1972), 2817-29, database is CAplus.
The addition of CH2N2 to acrylate esters (I; R = EtO, Ph, Me) and (II; R = Ph, Me) is governed only by electronic effects. Mixtures of 4-carbomethoxy-2-pyrazolines III (major products) and 3-carbomethoxy compounds IV (minor products) are obtained from I. 1-Pyrazolines V and 2-pyrazolines VI are the major and minor products, resp., in the addition of CH2N2 to II.
