-
Paragraph 0021; 0033, (2017/08/25)
The invention discloses a method for synthesizing 2 - substituted oxazoline or 2 - substituted oxazine new method, by nitrile and amino ethanol or 3 - amino - 1 - propanol as raw material, in the absence of solvent, can be used for the recycling of the sulfur to induce synthesis of 2 - substituted oxazoline and 2 - substituted piperazine. The method of the invention has low cost, simple reaction process, mild reaction conditions, the reaction time is short, the yield and the like, is suitable for the industrial generation.

Strong as an Ox: 2-Thiazoles and 2-oxazoles are formed by oxidation of 2-thiazolines and 2-oxazolines without requiring substituents at the C4 and C5 positions. DDQ plays an important role as the oxidant in this transformation and metal is unnecessary. This general procedure shows good functional group tolerance and provides a wide variety of 2-thiazoles and 2-oxazoles in moderate to excellent yields.
