In order to develop an useful synthestic process, we have synthesized amides with various substitutents. The isoquinoline skeleton was constructed through Bischler-Napieralski reaction, followed by asymmetric reduction of the imine intermediates with a Ru complex to form the only chiral center. Finally, we connected the two phenyl groups by Heck reaction and effectively obtained optically active aporphine alkaloids.

The results of in situ DRIFTS on propylene oxidation show that the allyl species originated from α-H abstraction of propylene were located at the wavenumbers of 1454 cm~(-1) and 1427 cm~(-1). The rate-determining step is the abstraction of an α-H abstraction from a lattice oxygen linked to a bismuth ion to form a π-allyl intermediate coordinated to a molybdenum ion. The metal-oxo group then attacks the allyl intermediate forming a σ-bonded oxygen-allyl species, which is in a rapid equilibrium with the π- bonded species. The σ-bonded species then transforms to acrolein by further abstraction of α-H. Such species as formate, carboxylate, carbonate transform to deep oxidation products. The acetone was derived from propylene by an enolic species at lower temperatures.
