Two complementary strategies employing organolithium chem. for the synthesis of glyoxal derivatives RC(O)R1R2 (R = methoxymethyl, 3,5-difluorophenyl, pyridin-2-yl, quinolin-6-yl, etc.; R1 = Cl, OEt, H; R2 = Cl, OEt, 3-chlorophenyl) were reported. Micro-mixer technol. allows for the generation of unstable organometallic intermediates and their instantaneous in-line quenching with esters as electrophiles RC(O)OEt. Selective mono-addition was observed via putative stabilized tetrahedral intermediates. Advantages offered by flow chem. technologies facilitate direct and efficient access to masked 1,2-dicarbonyl compounds while mitigating undesired byproduct formation. These two approaches enable the production of advanced and valuable synthetic building blocks for heterocyclic chem. with throughputs of grams per min.

Author is Tian, Wan-Fa; Hu, Chun-Hong; He, Ke-Han; He, Xiao-Ya; Li, Yang.

Herein, we have developed visible-light photoredox-catalyzed decarboxylating carboxylic acids for alkylation of heteroarenes under mild conditions. The transformation occurred smoothly without the requirement of stoichiometric oxidants in the presence of 0.3 equiv of base, which benefited from the release of hydrogen (H2) and carbon dioxide (CO2). Various substrates and functional groups were tolerated. Primary mechanistic studies suggest that an oxidative quenching pathway and a reductive quenching pathway are both possible in the catalytic cycle.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.
