Abstract

The present work deals with generation and synthesis of 2-(2- camphoryl)-4-(4-aryl)-4-oxobutanoic acids via Michael reaction condition depending on the type of nucleophilic reagents and medium (acidic or basic). The adducts are used as a key starting materials to synthesize some hetrocycles include pyridazinone, furanone, 1,2- oxazin-5-one, 1.2-diazapine, pyrane and hydroxyl pyridine derivatives. Steric factor plays an important role in regioselectivity. The structure of newly synthesized compounds were elucidated by elemental analysis and spectroscopic data.
