摘要:The invention relates to a process for the synthesis of moguisteine that is ethyl ester of (R,S)-3-[2-[(2-methoxyphenoxy)methyl]-1,3-thiazolidin-3-yl]-3-oxypropanoic acid which comprises the steps of forming a new cyclic intermediate of formula 2-[(2-methoxyphenoxy)methyl]-1,3-dioxolane (4), forming (R,S)-2-[(2-methoxyphenoxy)methyl]-1,3-thiazolidine (6) and reacting this latter with monoethylmalonic acid (7) or a salt thereof. The moguisteine of the invention is obtained in high yield and purity.

标题 :Biosynthesis of polyketide synthase substrates
发明人：KHOSLA CHAITAN; PFEIFER BLAINE
摘要:The use of enzymes which catalyze the production of starter and extender units for polyketides is described. In addition, modified loading modules are described, which can accept a variety of starting units such as substituted benzoates, and which can be used to generate substituted derivatives of natural products. These enzymes may be used to enhance the yield of polyketides that are natively produced or polyketides that are rationally designed. By using these techniques, the synthesis of a complete polyketide has been achieved in E. coli . Production can be enhanced in microbial organisms of polyketides and other secondary metabolites by delaying production until after exponential phase and by maintaining relatively constant nutrient levels in the medium. In addition, polyketide production can be enhanced by providing an expression system for a thioesterase II. Thus, by modifying the host organism and changing the culture conditions, synthesis of a secondary metabolite can be enhanced. The present invention also results in a host organism with desirable characteristics to be used in the production of such polyketides and to assess the results of gene shuffling.

权利人:SOLVAY SPECIALTY POLYMERS IT
摘要:A process for the manufacture of a (per)fluoropolyether amine comprising reacting a sulfonic ester of a (per)fluoropolyether alcohol with an excess of ammonia or organic amine at selected temperature is herein disclosed. The process allows obtaining (per)fluoropolyether amines, in particular primary, secondary and tertiary (per)fluoropolyether amines with high yields and selectivity and can be conveniently applied on an industrial scale.
