Stereoselective Synthesis of Meta- and Three-bridged Cyclophanes with Intramolecular Photocycloaddition by Using the Steric Effect of Methoxyl Group

Key Words: Cyclophane; stereoselectivity; conformation; regioisomer; photocycloaddition; torsional angle.Dimethoxymetacyclophanes 9 (n=2,3,4,5, and 6) and 10 were stereoselectively obtained in 61-87percent yields by means of photocycloaddition.

Synthesis of multi-bridged cyclophanes by means of [2 + 2] photocycloaddition. Stereocontrol of cyclobutane-linkage by methoxyl group

2,6-Divinylanisole derivatives 6 were irradiated in dry benzene under a nitrogen atmosphere to afford three-bridged cyclophanes 7 having exclusively anti-directed cyclobutane rings as linkages in 11 to 78% yields.
