Abstract
An updated and practical approach to the synthesis of dithymoquinone via one-step photoirradiation of thymoquinone (2-methyl-5-isopropyl-1,4-benzoquinone) is described. Synthesis resulted in a 55 % yield of one structural isomer (trans-anti derivative), as confirmed by HPLC, NMR spectroscopy and first ever single-crystal X-ray diffraction analyses.
