-
Paragraph 0009; 0010; 0011, (2019/12/25)
The invention relates to N-vinyl amide and a preparation method thereof. The preparation method comprises the following concrete steps: in the presence of triethylamine, reacting acyl chloride with 2-chloroethylamine hydrochloride to obtain corresponding N-(2-chloroethyl)amide, treating the N-(2-chloroethyl)amide with lithium diisopropylamide at room temperature, then adding halogenated hydrocarbon, carrying out a stirring reaction at room temperature for 4 hours, removing the solvent, and performing purification to obtain an N-vinyl amide compound. The preparation method of the invention is simple in synthetic route and uses easily-available raw materials; and the prepared N-vinyl amide compound is a good synthetic intermediate, and has potential biological activity and good application value.

A series of 1-(benzocycloalkyl)-4-(benzamidoalkyl)piperazine derivatives was prepared in order to obtain compounds with a high affinity and selectivity for 5-HT(1A) receptors. The modifications of aromatic substituents, the length of the alkyl chain, and the size of the ring were explored. Most of N-(1,2,3,4-tetrahydronaphthyl)-N'- (benzamidoethyl)piperazines (32-37) were bound to 5-HT(1A) receptors in a nanomolar range and presented a high degree of selectivity. After resolution, levorotatory enantiomers showed affinity and selectivity higher than those of dextrorotatory ones for 5-HT(1A) sites. The agonist type activity of selected derivatives was also confirmed in vitro on the inhibition of the activation of adenylate cyclase induced by forskolin and, in vivo, on the induction of the lower lip retraction in rats.
