Carbonylative Transformation of Allylarenes with CO Surrogates: Tunable Synthesis of 4-Arylbutanoic Acids, 2-Arylbutanoic Acids, and 4-Arylbutanals

In this Communication, procedures for the selective synthesis of 4-arylbutanoic acids, 2-arylbutanoic acids, and 4-arylbutanals from the same allylbenzenes have been developed. With formic acid or TFBen as the CO surrogate, reactions proceed selectively and effectively under carbon monoxide gas-free conditions.

A Comparative Study of Pyrolysis and Decarboxylation of β-Substituted t-Butyl Glycidates

A series of t-butyl glycidates (Ia-i) have been prepared by Darzens condensation of carbonyl compounds with t-butyl chloroacetate in the presence of potassium t-butoxide.The pyrolysis of these esters (I) and the decarboxylation of potassium salts of the corresponding acids result in the same higher aldehydes (II) though in varying proportions.The latter procedure has, however, been found to be superiour in all the cases.Structural assignments of I and II are based on elemental analyses and spectral data (IR, PMR).Resolution of cis- and trans-isomers of I has been achieved in three cases.
