The SNAr-type reaction of the piperidine amide of cyanoacetic acid with a series of heteroaryl halides followed by in situ oxidation of the resultant anion with peracetic acid provided a convenient, one-pot protocol for preparative access to heteroaryl alpha-keto amides. In this procedure, the amide of cyanoacetic acid functions as an Umpolung-type synthon of the alpha-keto amide moiety.

In this paper we wish to report on a variety of expedient chemical transformations and purifications achieved via a generic ‘catch and release’ methodology, based on a synthetically inert bipyridyl chelating tag that can be selectively captured with a resin-bound copper(II) species. Utilising this approach we are able to derive many of the same benefits associated with both solid phase synthesis and supported reagent methods. The Royal Society of Chemistry 2005.

In an article，Which mentioned a new discovery about 1448-87-9

A general and efficient protocol for direct C-H alkylation and acylation of N-heterocycles, using readily accessible carboxylic acids as radical precursors under visible-light irradiation without a photocatalyst and an additional acid additive, has been developed. This protocol provides expedient access to substituted N-heterocycles under mild and metal-free conditions. Mechanistic experiments indicate that this reaction proceeds through a visible-light-initiated radical chain propagation mechanism.
