Unprecedented, selective Nef reaction of secondary nitroalkanes promoted by DBU under basic homogeneous conditions
摘要:
Secondary nitrocompounds can be converted into the corresponding ketones under basic conditions using DBU in acetonitrile. Primary nitroalkanes are Unaffected by these conditions. (C) 2002 Elsevier Science Ltd. All rights reserved.

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.
