2-Substituted-1, 3-oxazolidines still remain actively studied nitrogen-containing heterocycles due to their effective application in medicine, agriculture, and polymer and paint and varnish industry [132]. Among fairly few synthetic approaches to 1, 3-oxazolidines, heterocyclization heterocyclization of vicinal aminoalcohols with various aldehydes and ketones occupies a special place. Depending on the activity of the starting reagents, the reaction time varies ...
