Synthesis and biological activity of N-substituted aminocarbonyl-1,3- dioxolanes as VLA-4 antagonists
A novel set of compounds with a 1,3-dioxolane ring which acts as a proline bioisostere have been successfully designed as VLA-4 receptor antagonists. Compounds (18e), (28j), and (35g) were shown to have high receptor affinities.
A simple method for the alkaline hydrolysis of esters
A very mild and rapid procedure for the efficient alkaline hydrolysis of esters in non-aqueous conditions has been developed, by the use of dichloromethane/methanol (9:1) as solvent. This method conveniently provides both carboxylic acids and alcohols from the corresponding esters and sodium hydroxide in a few minutes at room temperature. A plausible reaction mechanism is proposed.
