A new type of nucleophile, a 3-imino nitrile carbanion generated in situ by Thorpe reaction of acetonitrile with a base, was developed successfully and applied in a Pd-catalyzed asymmetric allylic alkylation with mono-substituted allyl reagents under Pd/S
Green synthesis method of nicotinic acid ester compounds based on non-metallic conditions
-
Paragraph 0058; 0061, (2021/09/29)
The invention discloses a green synthesis method based on nicotinic acid ester compounds under non-metallic conditions, and belongs to the technical field of organic synthesis. The method comprises the following steps of (III) replacing cyclopropanol and (II) substituted enamine ester as a raw material, taking tetramethyl piperidine nitrogen oxide as an oxidizing agent, 110 - 130 °C, stirring and reacting in an organic solvent to synthesize a (I) nicotinate compound. The invention provides a green synthesis method based on nicotinic acid ester compounds under non-metallic conditions, wherein cyclopropanols and enamine esters are taken as raw materials, and a polysubstituted nicotinate is synthesized through a strategy of oxidative dehydrogenation of ketene cyclization.

The silver-promoted intermolecular aminocyanation of alkynes for the synthesis of (Z)-β-aminoacrylonitriles is reported, using N-isocyanoiminotriphenylphosphorane (NIITP) as both the nitrile and amine source. The transformation proceeds in moderate to good yields, and in a regio- and stereoselective manner, using a wide range of acetylenes.
