    • General method for the synthesis of compounds 2-11 in MeOH: To a suspension of 100 mg (0.65 mmol, 1.1 equiv) of β-amino acid 1 in MeOH (5 mL), the required aldehyde (1 equiv) was added at room temperature. After stirring for 45 min at room temperature, t-butyl or cyclohexyl isocyanide (1 equiv) was added dropwise to the solution which was stirred for 3 days at an ambient temperature. Subsequently, the solvent was evaporated in vacuo, and water (5 mL) and chloroform (20 mL) were added. On extraction, drying and evaporation of the organic phase, the crude products 2-11 were obtained in yields of 43-76%.
