Synthesis of Enaminones and Their Reaction with Dimethyl Acetylene Dicarboxylate
In present paper a simple procedure for the synthesis of enaminones without catalyst from 1,3-diketones that reacted with primary or secondary amines in ethanol as solvent, as well as the reaction of enaminones with unsaturated esters such as dimethyl acetylene dicarboxylate are reported.

Cinco enaminonas 4a-e, derivadas da reação do ânion da 2,4,4-trimetil-2-oxazolina com acetato de etila, benzoato de etila, ciclohexanoato de etila, hexanoato de etila e p-metil benzoato de etila, respectivamente, foram preparadas e caracterizadas por RMNH, RMNC, FTIR e EM. As enaminonas 4a e 4b também foram analisadas pela técnica de difração de raios-X. A enaminona 4a cristalizou-se no sistema...
متن کاملEfficient construction of C-N and C-S bonds in 2-iminothiazoles via cascade reaction of enaminones with potassium thiocyanate.
A novel and highly efficient protocol has been developed for the regioselective synthesis of 2-iminothiazole derivatives with potential biochemical interest by the reaction of enaminones, potassium thiocyanate (KSCN), and N-bromo succinimide (NBS) under mild conditions. The reaction proceeds via the formation of α-bromo enaminones as a versatile intermediate followed by thiocyanation/intramolec...
