Mg-promoted reduction of ethyl cinnamate (1a) in the presence of carbon dioxide gave a mixture of β-carboxylated compound 2a and α,β-dicarboxylated compound 3a. Similar reductive carboxylation of 1a followed by acidic decarboxylation of one of the two geminal carboxyl groups of the generated 3a and esterification afforded selective formation of diethyl phenylsuccinate (2a) in good yield.
Direct access to β-oxodiazo compounds by copper(II)-catalyzed oxidative rearrangement of stabilized vinyl diazo derivatives
Barluenga, Jose,Lonzi, Giacomo,Riesgo, Lorena,Tomas, Miguel,Lopez, Luis A.
supporting information; experimental part, p. 18138 - 18141 (2011/12/21)
The copper(II)-catalyzed reaction of alkenyldiazo compounds with iodosylbenzene leading to β-oxodiazo derivatives is reported. This process occurs via an unprecedented 1,2-shift of the diazoacetate function. A selection of the synthetic applications of a
Formation of five-membered cyclic orthoesters from tribromides with participation of a neighboring carbonyl group
Gururaja, Guddeangadi N.,Mobin, Shaikh M.,Namboothiri, Irishi N. N.
experimental part, p. 2048 - 2052 (2011/05/16)
The Mg-mediated conjugate addition of bromoform to enones followed by alcoholysis of the resulting keto tribromides proceeds through an unusual course, affording cyclic orthoester (dihydrofuran) intermediates under neutral workup conditions. However, acid
