    摘要: The present invention discloses a method for directly constructing highly optically active tetrasubstituted allenic acid compounds, i.e., a one-step process for directly constructing highly optically active axially chiral tetrasubstituted allenic acid compounds by using tertiary propargyl alcohol, carbon monoxide and water as reactants in an organic solvent in the presence of palladium catalyst, chiral diphosphine ligand, monophosphine ligand and organic phosphoric acid. The method of the present invention has the following advantages: operations are simple, raw materials and reagents are readily available, the reaction conditions are mild, the substrate has high universality, the functional group has good compatibility, and the reaction has high enantioselectivity (90%∼> 99% ee). The highly optically active allenic acid compounds obtained by the present invention can be used as an important intermediate to construct γ-butyrolactone compounds containing tetrasubstituted chiral quaternary carbon centers, tetrasubstituted allenic alcohol and other compounds.

    摘要: The subject invention provides "no sat" canola oil. The subject invention also provides seeds that can be used to produce such oils. Plants that produce these seeds are also included within the subject invention. All of this was surprisingly achieved by using a delta-9 desaturase gene in canola. This technology can be applied to other plants as disclosed herein. Oils of the subject invention have particularly advantageous characteristics and fatty acid profiles, which were not heretofore attained. The subject invention still further provides a plant-optimized delta-9 desaturase gene. The subject invention still further provides a plant-optimized delta-9 desaturase gene. In some preferred embodiments, a preferred plant comprises at least two copies of a delta-9 desaturase gene of the subject invention. Seeds produced by such plants surprisingly do not exhibit effects of gene silencing but rather have further surprising reductions in levels of total saturates.
