Transformation of tricyclopentabenzene (trindane) to 12 - hydroxy - 16 - oxatetracyclo [10.3.1.01.5.07.11] hexadec -7(11) - en -2,6-dione

摘要

The present invention relates to a process for the transformation of tricyclopentabenzene to 12-hydroxy-16-oxatetracyclo[10.3.1.0^{1,5 .07,11 ]hexadec-7(11)-en-2,6-dione of formula 2} by ozonolysing two out of three double bonds of trindane, followed by aldol condensation and adding the hydroxyl group to the carbonyl function intramolecularly to obtain 12-hydroxy-16-oxatetracyclo[10.3.1.0^1,50^7,11]hexadec-7(11)-en-2,6-dione.
