20080312441Use of Oripavine as a Starting Material For Buprenorphine - There is provided a method for the synthesis of norbuprenorphine, and ultimately buprenorphine, utilizing oripavine as the starting material. Conventional methods of producing buprenorphine utilize thebaine as the starting material, requiring an O-demethylation step, typically a low to moderate yield transformation. The present use of oripavine as a starting material does not require an O-demethylation step, since the oripavine molecule lacks an O-3 methyl group.12-18-2008
20080312442Process for Preparing Morphinan-6-One Products with Low Levels of Alpha, Beta-Unsaturated Ketone Compounds - The present invention generally relates to processes for preparing highly pure morphinan-6-one products. The processes involve reducing the concentration of α,β-unsaturated ketone compounds present as impurities in morphinan 6 one products or reaction mixtures including morphinan 6 one compounds by treatment with a sulfur-containing compound.

20100035910Process for the Preparation of Quaternary N-Alkyl Morphinan Alkaloid Salts - An improved process for the N-alkylation of tertiary morphinan alkaloid bases to form the corresponding quaternary morphinan alkaloid derivatives.02-11-2010
20110082297Process for the Preparation of Quaternary N-Alkyl Morphinan Alkaloid Salts - An improved process for the N-alkylation of tertiary morphinan alkaloid bases to form the corresponding quaternary morphinan alkaloid derivatives.04-07-2011

20080276334Nucleic acid molecules and other molecules associated with plants - Expressed Sequence Tags (ESTS) isolated from soybean are disclosed. The ESTs provide a unique molecular tool for the targeting and isolation of novel genes for plant protection and improvement. The disclosed ESTs have utility in the development of new strategies for understanding critical plant developmental and metabolic pathways. The disclosed ESTs have particular utility in isolating genes and promoters, identifying and mapping the genes involved in developmental and metabolic pathways, and determining gene function. Sequence homology analyses using the ESTs provided in the present invention, will result in more efficient gene screening for desirable agronomic traits. An expanding database of these select pieces of the plant genomics puzzle will quickly expand the knowledge necessary for subsequent functional validation, a key limitation in current plant biotechnology efforts.11-06-2008
