An Efficient Synthesis of Enamides from Ketones
TL;DR: A new synthesis of enamides from ketones is disclosed that involves a phosphine-mediated reductive acylation of oximes, isolated in good yields and excellent purity, permitting a subsequent hydrogenation to access enantiopure acetamides at catalyst loadings practical for large-scale applications.

A ligand-free, copper-catalyzed cascade sequence to indole-2-carboxylic esters
TL;DR: A variety of indole-2-carboxylic esters are accessible in yields up to 61% through a ligand-free, copper-catalyzed reaction of a series of commercially available 2-halo aryl aldehydes with benign glycine amidoesters, including the common reagent ethyl acetamidoacetate.

Directed metalation and regioselective functionalization of 3-bromofuran and related heterocycles with NaHMDS
TL;DR: In this article, a mild and regioselective functionalization protocol for 3-bromofuran and analogs has been developed for selective metalation and functionalization.

TL;DR: In this article, a convenient method for converting oximes into enamides was proposed. But this method does not require the use of metallic reagents and does not produce the desired compounds without the concomitant production of a large volume of metallic waste.
