MAGNESIUM OXIDE AS AN EFFECTIVE CATALYST FOR MIGRATION OF <i>EXO</i>-CYCLIC DOUBLE BOND

Abstract

Abstract Exo-double bonds of 2-methylene-4,4,6-trimethylbicyclo[4,2,0]octane (1), Δ7(13)-protoilludene (3), Δ2(3),7(13)-illudadiene (5), and Δ2(10)-pinene (7) were effectively migrated to the endo positions over MgO catalyst.
