Reaction Conditions:
Stage #1: formaldehydwith sodium cyanide;ammonium acetate;water at 100; for 0.5 h;Green chemistry;
Stage #2: Benzoyl isothiocyanate at 100; for 0.333333 h;Green chemistry;
Stage #3: ethyl Bromopyruvate at 100; for 1 h;Green chemistry;
Steps:
2.3. General Procedure for the Preparation of Compounds 4
General procedure: The mixture of the aldehydes 1 (2 mmol), ammoniumacetate (5 mmol), NaCN (5 mmol) and KF/CP (10 mol%) inwater (5 mL) at 100 °C stirred for 30 min. After this timebenzoyl isothiocyanate 2 (2 mmol) was added slowly. Thismixture stirred for 20 min. After that, alkyl bromides 3 (2mmol) was added. After 1 h, the reaction completed and itwas confirmed by TLC. Finally, the reaction mixture cooledto room temperature and the solid residue was collected byfiltration. The solid was washed with EtOAc and KF/CP NPsseparated. The solvent was evaporated and the product 4 wasseparated as a solid form and purified by washing with theEt2O.
