Ester-directed orthogonal dual C-H activation and: Ortho aryl C-H alkenylation via distal weak coordination

An unprecedented orthogonal cross-coupling between aromatic C(sp2) and aliphatic olefinic C(sp2) carbons of two same molecules via dual C-H bond activation in an intermolecular fashion has been developed using a distal ester-directing group. This new coupling reaction led to the synthesis of the highly functionalized 1,3-diaryl molecular architecture in very good yields and with high chemo- and regioselectivities. In addition, using ester as the distal directing group, ortho C-H olefination of α-methyl aryl acrylates and cinnamic esters with various alkenes has been achieved in very good yields and with a wide range of substrate scope.

Visible light promoted metal- and photocatalyst-free synthesis of allylarenes

The metal- and photocatalyst-free synthesis of substituted allylarenes has been carried out under visible light driven conditions. The process was based on the photogeneration of aryl radicals from arylazo sulfones and their ensuing reaction with allyl sulfones. The developed procedure was very efficient when using substrates bearing electron-withdrawing groups, and allowed for the preparation of α-benzyl styrenes and 2-benzyl acrylates in good yields.

Microwave-assisted synthesis of the (E)-α-methylalkenoate framework from multifunctionalized allylic phosphonium salts

A convenient and general microwave-assisted method for the synthesis of stereochemically defined α-methylalkenoic acids and esters from allylic phosphonium salts in a basic aqueous medium is described. A selective preparation of acids or esters was dependent on the base (NaOH or NaHCO 3) employed in the reaction and could be achieved with good to excellent yields under mild conditions in the absence of hydrides and reducing agents.

Nitrogen ligands: The transition metal catalyzed reaction of aryl halides with olefins (Mizoroki-Heck), phenylboronic acid (Suzuki coupling) and Buchwald-Hartwig amination, new catalysts and effect of co-catalysts - Aryl halide activation - Part I

Nitrogen ligands are an excellent alternative for the traditional P-ligands in the Pd catalyzed Mizoroki-Heck reaction, Suzuki coupling and Buchwald-Hartwig aryl amination. Pd complexes of dimethyl glyoxime, 8-hydroxyquinoline, salen, picolinic acid, and DAB ligands gave high yields of the E-cinnamates and E-stilbenes from aryl iodides. Acetophenone oxime N, N-dimethybenzylamine and ferrocenyl oxime palladacycle are better catalysts with comparable yields, high TON (95, 000) and TOF's (2, 500 h-1) to P-ligand catalysts. Aryl bromides and in a few cases, aryl chlorides could also be activated by these complexes by the use of Lewis acid and (C 4H9)4NI as additives. Cy-DAB ligands gave good yields with electron rich aryl bromides and the use of ionic liquid improve the yield. These N-ligand metal complexes can be readily synthesized and the ligands possess the advantage of easy functional group modifications and convenient synthetic methods compared to P-ligands. The degradation reactions associated with P-ligands are not observed in the N-ligands, with comparable, high thermal, moisture and air stability and insensitivity. Activation of aryl bromides (Mizoroki-Heck reaction, Suzuki reaction) could be achieved in high yields, TON and TOF (86-94% yield, TON: 36, 000-90, 000, TOF: 6, 000-11, 500 h-1) catalyzed by monomeric amine and oxime palladacycles (Cat-8, 11, 13 B) with a N-heterocyclic carbene ligand better than a phosphorous ligand. Molten (C 4H9)4NBr is an efficient ionic liquid medium for the Mizoroki-Heck reaction of aryl bromides, giving higher yields. Low to moderate yields of aryl amination are obtained with the carbene palladacycle and N, N-dibenzyl piperazine Pd complexes.

The base-promoted fragmentation of the C-alkylation products (6a-h) and (8a-e) of methyl 4-oxothiolane-3-carboxylate (4) and methyl 2-methyl-4-oxothiolane-3-carboxylate (5) gave good yields of the α-substituted acrylates (7a-h) and α-substituted crotonate

An efficient preparation of α-substituted acrylic esters is described, based on the Dieckmann-Michael retrograde reactions of the C-alkylation products of 4-methoxycarbonylthiolan-3-one (1).
