Photooxygenation of natural ã-terpinene.
Photooxygenation reaction of ã -terpinene (1) in the presence of tetraphenyl porphine (TPP) or Rose Bengal (RB) gave 2, 5-dihydroperoxy-1-isopropylene-4-methylene-cyclohexane (2), 3,6-dihydroperorxy-3-isopropyl-6-methyl-2,4-cyclohexadiene (3) and 1,2&4,5-diepoxy-1-isopropyl-4-methylcyclohexane (4). The epoxide 4 was also synthesised through the epoxidation reaction of ã-terpinene (1) with m-chloroperbenzoic acid (mcpba).
