Synthesis of Tetrahydroisoindolinones via a Metal-Free Dehydrogenative Diels-Alder Reaction

A metal-free dehydrogenative Diels-Alder reaction of substituted alkenes for the synthesis of tetrahydroisoindolinones has been exploited for the first time. This new method features functional group tolerance and broad substrate scope, providing an efficient access to biologically active tetrahydroisoindolinone skeletons with endo steroselectivity in good to excellent yields. (Figure presented.).

ORGANOZINC REAGENTS AND PROCESSES FOR PREPARING AND USING THE SAME

Provided is an organozinc composition comprising (a) an organozinc complex carrying an allylic ligand, (b) a magnesium component and (c) a lithium component. The organozinc composition is useful as a synthetic intermediate with excellent reactivity and selectivity, and can be stored for extended periods of time without loss of activity. Moreover, a process for the preparation of the organozinc composition and synthetic procedures making use of the organozinc composition are provided.

Introduction of allyi and prenyl side-chains into aromatic systems by suzuki cross-coupling reactions

This paper reports some studies aiming at the developement of a general protocol useful for the synthesis of allyl- and prenylaromatic compounds. The first part deals with, the preparation of boron reagents like arylboronic acids and their pinacol esters as well as of pinacol allyl- and prenylboronates. The second part of the paper is devoted to the use of these boron reagents in Suzuki-Miyaura cross-coupling reactions leading to allylation and prenylation of aromatic compounds. Of the six methods studied, the most promising re-suits were obtained by using the Pd2(dba)3-catalyzed reactions of arylboronic acids with allyl and prenyl bromides, that lead to the products of cross coupling in high yields (average 87%), and the reactions of aryl trifluoroborates with allyl and prenyl bromides catalyzed by Pd(OAc)2 that lead to the products of coupling in all cases in high yields (average 82%).
