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 protocol of Pd(ii)-catalyzed, weak bidentate directing group assisted β-C(sp3)-H activation/cross-coupling with organoboron reagents has been achieved, affording arylation of aliphatic acid derivatives that contain α-hydrogen atoms in moderate to good yields. The potential of this method for an asymmetric β-C(sp3)-H arylation via desymmetrization was also presented.

RXRα represents an intriguing and unique target for pharmacologic interventions. We recently showed that Sulindac and a designed analog could bind to RXRα and modulate its biological activity, including inhibition of the interaction of an N-terminally truncated RXRα (tRXRα) with the p85α regulatory subunit of phosphatidylinositol-3-OH kinase (PI3K). Here we report the synthesis, testing and SAR of a series of novel analogs of Sulindac as potential modulators for inhibiting tRXRα-dependent AKT activation. A new compound 30 was identified to have improved biological activity.
A facile synthesis of 2-benzyloxy/2-(4-isopropylbenzyloxy)-2-methyl-3-(4- substituted phenyl)propanoic acid based insulin sensitizing agents: RSR 13-15 and PKR13-15

The title compounds (RSR13-15) and (PKR13-15) were prepared by the etherification of benzyl alcohol and 4-isopropylbenzyl alcohol respectively with ethyl-2-bromo-2-methyl-3-(4-substituted phenyl)propanoates in the presence of sodium hydride in THF followed by alkaline hydrolysis of the ethyl esters. The substituted propanoic acids used in this synthetic sequence were prepared by magnesium-methanol reduction of correspondingly substituted propenoic acids, which in turn were prepared via 'Perkin Reaction' of 4-substituted benzaldehydes with propanoic anhydride. The details of the synthetic sequence followed for the preparation of all these compounds having almost all the structural features required for a compound to act as a potent insulin sensitizing agent are reported.
