Efficient Approach to Medium-sized Cyclic Molecules Containing (E)-Alkene via Z to E Photochemical Isomerization in the Presence of AgNO3-impregnated Silica Gel

Efficient synthesis of medium-sized cyclic molecules containing an (E)-alkene was performed via the highly (E)-selective photochemical isomerization of the (Z)-isomer, facilitated by AgNO3-impregnated silica gel.
