Applicant, in the experiment with one pot process oxazoline-zinc chloride coordination compound, has unexpectedly obtained another kind ofization Compound salicylamide.
Three, summary of the invention
It is desirable to provide compound salicylamide, to be solved technical problem is that one-step synthesis obtains target and produces Thing.
This synthetic method includes synthesis and separates, and described synthesis is salicylonitrile with D-phenylalaninol at chlorobenzene Solvent has the anhydrous PtCl of catalyst4In the presence of under the conditions of anhydrous and oxygen-free back flow reaction 60 ~ 70 hours, PtCl4Consumption be former 39.8 mol % of doses;
Reaction is sloughed chlorobenzene after terminating, is added 40mL water stirring and dissolving, then extracts with chloroform, after extraction phase drying, precipitation Upper silica gel column chromatography separates, and is 1:100 eluting by volume with petroleum ether/dichloromethane, collects last component point, slough eluting Target product salicylamide is obtained after agent.
Synthetic reaction is as follows:
This synthetic method one step obtains target product, and technique is simple, easy to operate.
This reaction mechanism can be speculated as salicylonitrile under the strong lewis acid platinum tetrachloride effect of 39.8 mol%, Meeting hydrone and carry out nucleophilic addition, product is salicylamide.
