Five-Membered Oxaza Heterocyclic Compounds on the Basis of Epoxides and Aziridines

The review summarizes methods for the synthesis of 1,3-oxazolidin-2-ones, 1,3-oxazolidines, and dihydro-1,3-oxazoles from epoxides and aziridines. Possible applications of N,O-containing heterocycles in medicinal and organic chemistry as biologically active substances and intermediate products for their preparation are considered.
