General procedure for the preparation of compounds 3a-h: To a magnetically stirred solution of β-aminoketone (1 mmol) and triphenylphosphine (0.28 g, 1 mmol) in CH2Cl2 (10 mL, was added dropwise a mixture of dialkyl acetylenedicarboxylate (1 mmol) in CH 2Cl2 (5 mL) at room temperature. The reaction mixture was stirred for 24 h, then the solvent was removed under reduced pressure and the residue was purified by silica gel column chromatography (hexane-EtOAc, The solvent was removed under reduced pressure to afford the product. 3a: White powder; mp 110-112 ° C; IR (KBr, 1740, 1699 (ester) cm-1; Anal. Calcd for C21H20BrNO5: C, 56.52; H, 4.52; N, 3.14.
