| Abstract: | The photolysis of musk ketone in cyclohexane and methanol afforded several cyclization products while the product spectrum in cyclohexene and squalene was characterized by an amino derivative and a ring expansion product, respectively. On cellulose stearate layers the photochemical reactions of musk ketone proceeded readily both under sun simulator and in natural sunlight and several photoproducts identified in solvent experiments were detected. Photoproducts were isolated by preparative HPLC and TLC and analyzed by means of HPLC, GC/MS, MS, LC/MS, 1H‐ and 13C‐NMR. |
