✦ Synopsis

Reaction of Pentaeyclo[5.4.0.02,6.03'10.05'9]

undecmle-8,l l-dione (l) with ethanedithiol, when performed in the presence of a Lewis acid catalyst (F3B-OEt2), afforded the corresponding mono(ethylene dithioacetal), 2, along with 7,8-[(thicethano)thio]pentacyclo[6.3.0.02,6.03, lO.05,9]undecan-l 1-one mono(ethylene dithioacetal) (3). Raney nickel reduction of 2 resulted in hydrogenolysis of both the dithioacetal moiety and the cyclobutane ring in 2 and led to the formation of a complex mixture of products (7-10). In contrast to this result, Raney nickel reduction of 3 afforded a single product, i.e., 7,8-[(thioethano)thio]pentacyclo [6.3.0.02.6.03,10.05,9]tmdecane (It)in 35% yield.

Abstractz The reactions of 3,6-dibromo-2,7-dioxotetracyclo[6.3.0.0 4s".6s9]undecane with organomagnesium halides are investigated as a method of preparing unusual tetrasubstitutcd pentacycloundwanes (D,-trishomocubanes). The tetrasubstituted pentacycloundeames have been characterized and product geo
