CYCLOHEXENONE CARBOXYLATES. A VERSATILE SOURCE FOR FUSED ISOXAZOLES AND PYRAZOLES
摘要:
The 6-carbethoxy-3,5-diarylcyclohex-2-enone (1) was subjected to condensation and 1.3-dipolar cycloaddition reactions to get fused isoxazole and pyrazole derivatives.

iron-salt-catalyzed carbon–carbon bond cleavage occurring through a retro-Claisen condensation reaction has been developed. The reaction is useful for the synthesis of a variety of esters or ketones under mild conditions. This method works under solvent-free conditions without the need of an inert atmosphere. This protocol is also applicable for the one-pot syntheses of ketones through tandem carbon–carbon bond
A new syntheticroute was developed for the synthesis of 4,6-diaryl-2-methyl-l,3-benzoxazoles and their hydrogenated derivatives. The target compounds were obtained via the Neber rearrangement from 3,5-diaryl-2-cyclohexen-l-ones. The formation of the isomers in the dihydro derivatives was explained by the [1,5] sigmatropic shift of hydrogen under thermal condition. DDQ was employed for the dehydrogenation
