To develop a nicotinamide-independent single flavoenzyme system for the asymmetric bioreduction of C=C bonds, four types of hydrogen donor, encompassing more than 50 candidates, were investigated. Six highly potent, cheap, and commercially available co-substrates were identified that (under the optimized conditions) resulted in conversions and enantioselectivities comparable with, or even superior to, those obtained with traditional two-enzyme nicotinamide adenine dinucleotide phosphate (NAD(P)H)-recycling systems.

Configuration of the oxirane ring in stereoisomeric 3,4-epoxycaranes affects the direction of their skeletal rearrangements in liquid (HSO3F-SO2FCl) and over solid (TiO2/SO42-) superacids; in the latter case, compounds postulated as intermediates in the liquid-phase process have been isolated.

The details of the rearrangement of some isopimaranes in the presence of boron trifluoride etherate are presented and explained.As a result of comparative studies with terpenoids in the presence of BF3, it is proposed that the complex of this Lewis acid with ketones acts as a Bronsted acid in the equilibration of double bonds.It is also suggested that natural products with the carbon skeleton of the rearrangement product should be encountered in nature.
