Access to multi-functionalized oxazolines via silver-catalyzed heteroannulation of enamides with sulfoxonium ylides

Disclosed herein is an efficient Ag-catalyzed [4 + 1] heteroannulation reaction of enamides with α-carbonyl sulfoxonium ylides. The diastereoselective transformation provides a practical access to a diverse range of multi-functionalized oxazoline derivatives. The synthetic utility of the resultant tetra-substituted oxazolines is further demonstrated by a series of useful manipulations into valuable building blocks of pharmaceutical relevance.

Preparation method of N-vinyl alkylamide

The invention relates to the technical field of vinyl compound production, in particular to a preparation method of Nvinyl alkyl amide. The preparation method comprises the following steps: A) under the action of a composite basic catalyst, reacting acetaldehyde with alkylamide to obtain Nhydroxyethyl alkylamide, and carrying out esterification reaction on the obtained Nhydroxyethyl alkylamide andacid anhydride to obtain an ester compound; wherein the composite basic catalyst comprises an inorganic base and an amine compound; and B) carrying out medium-temperature cracking on the ester compound, and carrying out vacuum distillation to obtain the Nvinyl alkylamide. Research finds that inorganic base and amine compounds are adopted as catalysts at the same time, so that the dosage of a basic catalyst required by reaction of Nhydroxyethyl alkylamide and anhydride can be remarkably reduced, the temperature required by subsequent cracking reaction is reduced, a reaction system tends to bemilder, and the reaction yield is improved. The yield and the purity of a reaction product can be remarkably improved while the energy consumption is reduced.

PROCESS FOR PRODUCING HIGH-PURITY N-VINYLCARBOXAMIDES

Disclosed is a process for producing high-purity N-vinylcarboxamides comprising: (A) a step of dissolving a crude N-vinylcarboxamide in an alcohol having 1 to 3 carbon atoms, the crude N-vinylcarboxamide containing 50 to 97% by mass of an N-vinylcarboxamide; (B) a step of adding an aliphatic hydrocarbon having 5 to 10 carbon atoms to the composition obtained in the step (A) to precipitate a crystal of the N-vinylcarboxamide; and (C) a step of separating the crystal of the N-vinylcarboxamide precipitated in the step (B).
