872-32-2, General procedure: General protocol for the preparation of alkynyl imines Ml-6. percent [0070] To a solution of freshly distilled diisopropylamine (6.5 mmol, 0.93 mL) in anhydrous THF (10 mL) at 0 ¡ãC was added slowly a solution of “butyllithium (1.6 M in hexanes, 3.75 mL, 6.0 mmol, 1.2 equiv.) under argon atmosphere. After 20 min this solution was cooled to -78 ¡ãC and a solution of cyclic imine 3 (5.0 mmol) in anhydrous THF (5.0 mL) was added dropwise. The resulting mixture was then stirred at -78 ¡ãC for 2 h. A solution of alkyl iodide 4 (6.0 mmol, 1.2 equiv.) in anhydrous THF (5.0 mL) was added slowly, after which the reaction mixture was slowly warmed to 23 ¡ãC and stirred overnight. An aqueous solution of sodium hydroxide (0.5 M, 20 mL) was then added and the aqueous layer was extracted with ether. The combined organic phases were washed with a solution of sodium hydroxide (0.5 M), dried over anhydrous Na2S04. After filtration, the solvent was removed in vacuo to give the residue, which was used in the next step without further purification.
872-32-2 2-Methyl-1-pyrroline 70103, apyrrolines compound, is more and more widely used in various fields.
