Site- and Stereoselectivity in the Photochemical Oxetane Formation Reaction (Paternò-Büchi Reaction) of Tetrahydrobenzofuranols with Benzophenone
The Paternò-Büchi reactions of tetrahydrobenzofuranols with benzophenone were investigated to reveal site- and stereoselectivity in oxetane formation reactions. Both selectivities were found to be largely dependent on the reaction temperature. The trans selectivity increased with a decrease in tempe...

| Zusammenfassung: | The Paternò-Büchi reactions of tetrahydrobenzofuranols with benzophenone were investigated to reveal site- and stereoselectivity in oxetane formation reactions. Both selectivities were found to be largely dependent on the reaction temperature. The trans selectivity increased with a decrease in temperature, and the more-substituted oxetanes were selectively formed at high temperature. |
