The Michaelreaction of various nitroalkanes with conjugatedenones can be performed in NaOH 0.025 M and in the presence of cetyltrimethylammonium chloride (CTACl) as cationic surfactant, without any organic solvent. Good yields of the products are obtained even with hindered starting materials.
Treatment of secondary nitroalkanes with neat silica-supported 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD), at room temperature, allows the direct conversion of the secondary nitro groups to the corresponding keto carbonyls.
