A versatile, robust, and stereocomplementary synthesis of fully-substituted (E)- and (Z)-stereodefined α,β-unsaturated esters 3 from accessible α-substituted β-ketoesters 1via (E)- and (Z)-enol phosphonates was achieved. The present method involves two ac

The intramolecular cycloadditions of some mono(allyloxy)- and bis(allyloxy)perchlorocyclopentadienes have been carried out.Even in the case of trisubstituted olefins, this internal cycloaddition process occurs in good yield.The allyloxy compounds (10, 11,
SYNTHESIS, MOLECULAR PROPERTIES AND PHARMACOLOGICAL ACTIVITY OF SOME p-SUBSTITUTED (E)- AND (Z)-α,β-DIMETHYLCINNAMIC ACIDS

A series of p-substituted (E)- and (Z)-α,β-dimethylcinnamic acids has been prepared and pharmacologically tested.The configurations of the acids prepared were determined from their NMR spectra.The UV spectra and the acid dissociation constants are reported.The collected data show that an extensive conjugation between the aryl and carboxy groups via the double bond does not exist, due to the steric hindrance of the α,β-dimethyl substitution on the cinnamic system.
