The synthesis of new isoxazole-containing arylcyclopentenyl sulfones is presented by the ring-closing metathesis reaction (RCM).
Aim. To develop the preparative methods for the synthesis of new potential biologically active 3-aryl-5-[1-(aryl-4-sulfonyl)-cyclopent-3-enyl]isoxazoles obtained by RCM.
Results and discussion. A number of new sulfones with an active methylene group was obtained by the interaction of bromo derivatives of isoxazoles with sodium salts of sulfinic acids. By alkylation of the active methylene group with allyl bromide a number of new diallyl derivatives was synthesized. The target isoxazolecontaining arylcyclopentenyl sulfones were synthesized from the diallyl derivatives obtained using the ruthenium-carbene catalyst.
Experimental part. The synthesis of the starting and target compounds was performed under classical preparative conditions; the methods of column chromatography; elemental analysis; LCMS; 1H and 13C NMRspectroscopy were used.
Conclusions. The synthetic sequence for preparation of new isooxazole-containing aryl cyclopentenyl sulfones has been developed using RCM at the final stage.
