    • Representative procedure for the preparation of compounds 3a, 4a: a mixture of sarcosine (89 mg, 1.0 mmol), benzaldehyde (106 mg, 1.0 mmol) and 1 (195 mg, 1.0 mmol) in dry toluene (30 mL) containing molecular sieves (500 mg, 3 Å) was heated at reflux with stirring for 5 h. The solvent was then removed under reduced pressure and the residue was subjected to column chromatography on silica gel using hexane-ethyl acetate (9:1) as eluent to give the products.
