Abstract:
Irradiation of (E)-3-(p-methoxyphenyl)-3-pentenyl, (E)-4-(p-methoxyphenyl)-4-hexenyl, and (E)-5-(p-methoxyphenyl)-5-heptenyl 9-phenanthrenecarboxylates (B-2E, B-3E, and B-4E, respectively) in benzene gave intramolecular [2+2] cycloadducts, cyclobutane derivatives (CB-2, CB-3, and CB-4, respectively) possessing the same conformation as an intermolecular [2+2] cycloadduct (CB-0) between methyl 9-phenanthrenecarboxylate (9-MCP) and trans-anethole (t-AN), and oxetane derivatives (OX-2, OX-3, and OX-4, respectively) arising from intramolecular cycloaddition between the carbonyl group and the olefinic double bond. However, (E)-4-(p-methoxyphenyl)-3-butenyl and (E)-5-(p-methoxyphenyl)-4-pentenyl 9-phenanthrenecarboxylates (A-2E and A-3E, respectively) afforded only products derived from oxetane precursors.
