Abstract
Cycloheptatriene undergoes highly peri- and diastereo-selective [6 + 2 ]-cycloaddition reactions with 1-oxadienes in the presence of catalyti c amounts of eta(4)-oxadiene molybdenum complexes under mild condition s; the stereochemistry of a cycloadduct derivative 6 and that of the c orresponding tungsten oxadiene complex suggests that cycloheptatriene attacks the oxadiene from the metal free side.
