标 题:A cytochrome p450 enzyme associated with the synthesis of delta-12 -epoxy groups in fatty acids of plants
发明人：CAHOON EDGAR B
权利人:DU PONT
摘要:An isolated nucleic acid fragment encoding a cytochrome P450 enzyme associated with the synthesis of plant DELTA12-epoxy fatty acids is disclosed. The invention also relates to making a chimeric construct encoding all or a portion of the cytochrome P450 enzymes associated with the synthesis of plant DELTA12-epoxy fatty acids, in sense or antisense orientation, wherein expression of the chimeric construct results in production of altered levels of the cytochrome P450 enzymes associated with the synthesis of plant DELTA12-epoxy fatty acids in a transformed host cell.

标 题 :Synthesis of esters of acetylenic alcohols
发明人：CLOSE RALPH E; OROSHNIK WILLIAM
权利人:SCM CORP
摘要:A process for the synthesis of perfume products, Vitamin E and intermediates described herein involving a coupling reaction. For instance, a process for the synthesis of dehydrophytol and Vitamin E comprising forming a C15 acetylene from hexahydropseudoionone and then coupling said acetylene with 1-acetoxy-4-chloro-3-methylbut-2-ene to form a C20 acetoxy-enyne. The latter is readily subjected to partial hydrogenation and saponification in that order to form a dehydrophytol, a useful intermediate for the synthesis of Vitamin E and other products.

标题:Synthesis of acetylenic compounds useful in preparing dehydrophytols and Vitamin E
发明人：CLOSE RALPH E; OROSHNIK WILLIAM
权利人:SCM CORP
摘要:A process for the synthesis of an acetylenic hydrocarbon from an acetylenic carbinol which involves first replacing the hydroxyl group of the carbinol with a halogen to form a propargylic halide, dehalogenating the propargylic halide to form an allene, and isomerizing said allene to the desired acetylene. The present invention is particularly useful in the synthesis of Vitamin E.
