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.

We describe herein a synthetically useful method for the enantioselective intermolecular Heck-Matsuda arylation of acyclic allylic alcohols. Aryldiazonium tetrafluoroborates were applied as arylating agents in the presence of Pd(TFA)2 and a chiral, commercially available, bisoxazoline ligand. The methodology is straightforward, robust, scalable up to a few grams, and of broad scope allowing the synthesis of a range of β-aryl-carbonyl compounds in good to high enantioselectivities and yields. This new enantioselective Heck-Matsuda arylation allowed the synthesis of β-aryl-γ-lactones and β-aryl aldehydes, which play a vital role as key intermediates in the synthesis of the biologically active compounds, such as (R)-baclofen, (R)-rolipram, (S)-curcumene, (S)-dehydrocurcumene, and (S)-tumerone.

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.
