Recent progress in the synthesis of morpholines

The morpholine (1,4-oxazinane) motif attracted significant attention due to its widespread availability in natural products and biologically relevant compounds. This review describes recent advances in the synthesis of morpholines and their carbonyl-containing analogs from 1,2-amino alcohols, aziridines, epoxides, and related compounds. Special attention is paid to the syntheses performed in a stereoselective manner and using transition metal catalysis. Selected works published since 2013 are covered.
