This minireview presents the synthesis and applications of enaminones, enaminoesters, and related compounds. A metal‐free synthesis of pyridines and fused pyridines, pyridyl‐substituted amino acids, hydroxy acids, and polyols which is enabled by ring switching methodology is described, as well as a simple metal‐free synthesis of aryl‐substituted pyridines, and polysubstituted pyridines from polysubstituted butadiene.

“…-naphtho[1,2-b]pyran-2-one 242a,b[141], as shown in Scheme 74.Pyrano[3,2-h]quinolines 245 have been synthesized via the reaction of 8-hydroxyquinoline 243 with the arylidine 244 in refluxing ethanol containing a catalytic amount of piperidine. Compounds 245 were visualized to be formed through the addition of quinolinyl C-7 to the electronically deficient -C of the cinnamonitrile [142] (Scheme 75).When equimolar amounts of the activated nitrile 244a,b and 3-methyl-1-phenylpyrazol-5-one as an active methylenecontaining heterocyclic compound were refluxed in absolute the presence of piperidine as a catalytic base.…”

New developments in the utilities of some carbon nucleophiles in heterocyclic synthesis are reviewed. General synthetic routes based on the utilization of carbon nucleophiles of active methylene are discussed. The major methods and modifications are analyzed. Heterocycles are ubiquitous in all kind of compounds of interest, and among all the possible synthetic methods of achieving their introduction into a structure, probably the use of a carbon nucleophile analogues are the most direct one. The present review deals with the generation and synthetic of carbon nucleophile, which uses as scaffold for the heterocyclic synthesis, and can be considered as an update review. Therefore the only references published upon the second quarter of 2003 are included, and the same restrictions to the literature coverage apply.
