- The compound features a saturated six-member morpholine ring composed, in sequence, of an oxygen at position 1, a chiral carbon at position 2, a methylene at position 3, a nitrogen at position 4, and two additional methylenes at positions 5 and 6 that close the ring back to the oxygen.
- The chiral carbon at position 2 (S configuration) bears an ethyl substituent.
- The ring nitrogen at position 4 is bonded to an imine carbon that carries a hydroxyl group.
- This imine carbon is double-bonded to a nitrogen, which is attached to a second chiral carbon (R configuration) that carries both a methyl group and a morpholin-4-ylmethyl group.
- The morpholin-4-ylmethyl group is derived from a morpholine ring in which the nitrogen and oxygen occupy the 1,4-positions, with the methylene linker attaching to the ring nitrogen from the second chiral carbon.
