The invention relates to agents for use on skin or hair, particularly for increasing skin tanning and the synthesis of melanin in skin or hair. The invention contains, in particular, cosmetic or dermatological preparations containing quadruply substituted cyclohexene compounds. The use of the preparations leads to the induction and intensification of the tanning mechanisms of skin, the intensification of hair color and thus also to an intensification of the skin's and hair's intrinsic protection.
A novel strategy for the synthesis of 2-aroylthienothiazoles via C H/N O bond functionalization of ketoximes is developed. This reaction features excellent step- and atom-economy, as well as broad substrate scope. Various common ketoximes, even vinyl ketoximes, were efficiently converted to 2-aroylthienothiazoles. Preliminary mechanistic studies indicated that the radical process should be involved in this transformation. Moreover, the product exhibited good coordination with Cu(II), showing the potential application in the metal coordination field.
