Masaki Ue; Masahiko Kinugawa; Kiyomi Kakiuchi; Yoshito Tobe; Yoshinobu Odaira

Abstract The photoreaction of 2-naphthols 1a-e with ethylene in the presence of aluminum halide gave the [2+2] cycloadducts 3a-e in good yields.

Masaki Ue; Hiroshi Tsukahara; Kazuya Kobiro; Kiyomi Kakiuchi; Yoshito Tobe; Yoshinobu Odaira

cis,trans-Tricyclo[6.3.0.01,4]undecan-5-one (2) rearranged under acidic conditions through unusual pathways to give cis,cis-tricyclo[6.3.0.01,5]undecan-4-one (3). The application to the α-methylene derivative of 2 afforded the angularly fused triquinane having an α-methylenecyclopentanone unit.
