Catalytic intramolecular C-H amination and aziridination reactions of o-allylphenyl azidoformates have been achieved under visible-light irradiation, providing a mild, clean, and efficient method for the synthesis of useful benzoxazolones and [5.1.0] bicyclic aziridines. Mechanistic studies suggest that a triplet nitrene acts as the reactive intermediate. The chemoselectivity of the reaction, with alkyl olefin aziridination ? electron deficient olefin aziridination ≈ C(sp2)-H amination ? C(sp3)-H amination was observed, which may be instructive in the development of an understanding of visible-light-induced triplet nitrene transformation reactions.

The evaluation of a series of piperazinyl carbamates and ureas, designed on the basis of previously reported TRPV1 antagonists and FAAH inhibitors, led to the identification of some 'dual-action' compounds targeting both FAAH and TRPV1 or TRPA1 receptors.
Heat-sensitive recording materials and phenol compounds
-
, (2008/06/13)
Heat-sensitive recording materials contain an electron-donating chromogenic compound and an electron-attracting compound. The recording materials also contain at least one compound represented by the following formula: STR1 wherein R1 and R3 mean a hydrogen atom or an alkyl, aralkyl or aryl group, R2 and R4 denote an alkyl, alkenyl, aralkyl or aryl group, X1, X2, Y1 and Y2 stand for an oxygen or a sulfur atom, and --Z1 -- and --Z2 -- are a specific aromatic group. Also provided are phenol compounds represented by the following formula: STR2 wherein R1, R2, X1 and Y1 have the same meanings as defined above; R5 and R6 are a hydrogen or halogen atom or an alkyl, alkoxy, aralkyl, aryl or hydroxyl group; p and q stand for an integer of 1-4; R5 and R6 may be either the same or different when p and q represent an integer of 2 or greater; and --Z3 -- means a specific divalent group.
