Synthesis of 4-Substituted 5,6-Diphenylmorpholine-2,3-diones With Two or Three Chiral Centers
Chiral α-aminoalcohols obtained by stereoselective reduction of α-iminoketones have been condensed with oxalyl chloride to afford 4-substituted 5,6-diphenylmorpholine-2,3-diones having two or three chiral centers.
