Abstract The absoluteconfiguration of the acetyleniccompoundfalcarindiol is established as (3R,8S) and falcarindiol is thus (+)-(3R,8S)-(Z)-heptadeca-1,9-dien-4,6-diyn-3,8-diol. (R)-Heptadecan-8-ol and (S)-heptadecan-8- ol are synthesized and (3R,8S)-heptadecan-3,8-diol is characterized.

The present invention provides catalysts, methods, and reactor systems for converting oxygenated hydrocarbons to oxygenated compounds. The invention includes methods for producing cyclic ethers, monooxygenates, dioxygenates, ketones, aldehydes, carboxylic acids, and alcohols from oxygenated hydrocarbons, such as carbohydrates, sugars, sugar alcohols, sugar degradation products, and the like, using catalysts containing palladium, molybdenum, tin, and tungsten. The oxygenated compounds produced are useful in the production of liquid fuels, chemicals, and other products.

Methods and compositions for the production of oil, fuels, oleochemicals, and other compounds in recombinant microorganisms are provided, including oil-bearing microorganisms and methods of low cost cultivation of such microorganisms. Microalgal cells containing exogenous genes encoding, for example, a lipase, a sucrose transporter, a sucrose invertase, a fructokinase, a polysaccharide-degrading enzyme, a keto acyl-ACP synthase enzyme, a fatty acyl-ACP thioesterase, a fatty acyl-CoA/aldehyde reductase, a fatty acyl-CoA reductase, a fatty aldehyde reductase, a fatty acid hydroxylase, a desaturase enzyme, a fatty aldehyde decarbonylase, and/or an acyl carrier protein are useful in manufacturing transportation fuels such as renewable diesel, biodiesel, and renewable jet fuel, as well as oleochemicals such as functional fluids, surfactants, soaps and lubricants.
