Facile synthesis of highly functionalized stable ketenimines by a three-component reaction of alkyl isocyanides, dialkyl acetylenedicarboxylates and ethyl carbazones
Anary-Abbasinejad, Mohammad,Anaraki-Ardakani, Hossein,Ghanea, Fatemeh
body text, p. 397 - 400 (2010/05/01)
The reactive intermediate generated by the reaction of alkyl isocyanides and dialkyl acetylenedicarboxylates was trapped by ethyl carbazones to produce stable ketenimine derivatives in good yield. The reaction is characterized by mild conditions, high sel

Page/Page column 34-37, (2008/06/13)
The present invention relates to a delivery system in the form of a dynamic mixture obtained by reacting together, in the presence of water, at least one hydrazine derivative with at least one perfuming, flavoring, insect repellent or attractant, bactericide and/or fungicide aldehyde or ketone. The invention's mixture is capable of releasing in a controlled and prolonged manner said aldehyde or ketone in the surrounding environment. Furthermore, the present invention concerns also the use of said dynamic mixtures as perfuming ingredients as well as the perfuming compositions or perfumed articles comprising the invention's mixtures.
X=Y-ZH SYSTEMS AS POTENTIAL 1,3-DIPOLES. PART 20. DECARBOXYLATION OF α-IMINO ACIDS. MECHANIZM AND APPLICATIONS TO THIOAMIDE SYNTHESIS

α-Imino acids, prepared from α-keto acids and primary amines, undergo facile decarboxylation to the corresponding imines on heating at =80 deg C in benzene or methylene chloride.Decarboxylation proceeds via a 1,2-ylide which can be trapped by sulphur to give the corresponding secondary thioamides in good yield. 1,2-Ylides from secondary amines and α-keto acids can be generated in situ and trapped with sulphur to give tertiary thioamides in excellent yield.
