Reactions of functionally substituted bicyclo[4.2.2]deca-2,4,7,9-tetraenes with m-chloroperbenzoic acid and in vitro evaluation Of Product Cytotoxicity against tumor cells

The oxidation of functionally substituted bicyclo[4.2.2]deca-2,4,7,9-tetraenes with m-chloroperbenzoic acid affords practically valuable 8-oxatricyclo[4.3.2.0^7,9]undeca-2,4,10-trienes and bicyclo[4.3.1]deca-2,4,8-triene-7,10-diols in yields of 65–72%. The structures of the products were established by advanced spectral methods and X-ray diffraction analysis. The new compounds were screened for in vitro cytotoxicity against Jurkat, K562, U937 and HL60 tumor cell lines.
