Oxidative Kinetic Resolution of cis -Fused Tricyclic 1-Tetralone Derivatives by Guanidine-Bisurea Bifunctional Organocatalyst

We present an enantioselective synthesis of cis -fused tricyclic 1-tetralones via oxidative kinetic resolution in the presence of cumene hydroperoxide (CHP) and guanidine-bisurea bifunctional organocatalyst. This reaction affords the corresponding α-hydroxylation products together with unreacted tetralones in good to high enantioselectivity, with s values as high as 42. The reaction was successfully applied for the synthesis of the core structure of a kainoid derivative, 4-(2-methoxyphenyl)-2-carboxy-3-pyrrolidineacetic acid (MFPA).

Metal-catalyzed organic photoreactions. Photoreaction of 2-chloroacetophenone derivatives with olefins in the presence of silver trifluoromethanesulfonate

UV-irradiation of 2-chloroacetophenones and olefins in the presence of silver triflate affords naphthalenone derivatives with high regio and stereoselectivity and chemical yields. A possible mechanism is proposed.

METAL-CATALYZED ORGANIC PHOTOREACTIONS. PHOTOREACTION OF OLEFINS WITH 2-CHLOROACETOPHENONE IN THE PRESENCE OF SILVER TRIFLUOROMETHANESULFONATE

Under UV irradiation with 2-chloroacetophenone in the presence of silver trifluoromethanesulfonate in acetonitrile, acyclic olefins gave naphtalenone derivatives, while cyclic olefins gave phenantrone derivatives in moderate yields.
