Article

Summary

The results of experiments on the UV irradiation of six coumarins and the study of the products formed have shown that acylated derivatives of khellactone undergo photolysis with the successive splitting out of acyl residues at C4′, and then at C3′, followed by the dehydration of the resulting diol and the formation of 3′-hydroxyseselin. The hypothesis has been put forward that dihydrocoumarins containing a more voluminous substituent in the 4′ position are the most sensitive to light.
