摘要:A method for the synthesis of 5-aryl-1,3,3,-trimethyl-2-methylene-indoline derivatives of Formula (I) or its salts of Formula (Ia) wherein 1 mole of a 5-aryl-2,3,3-trimethyl-3H-indole derivative of Formula (VII) is reacted for 1 to 44 hours at a temperature of 20° to 180° C. in an apolar, aprotic or polar, protic or polar aprotic solvent with 1 to 50 moles of a compound of Formula R1-A; new compounds of Formulas (I)/(Ia) and (V), obtainable by this method as well as an agent containing at least one compound of Formula (I)/(Ia) and a carbonyl/imine compound for dyeing keratinic fibers and a method for temporarily dyeing keratin fibers, for which the keratin fiber is dyed with the aforementioned agent and the dyeing, so obtained, is removed again at any later time by a sulfite preparation.

标题 :Plants with elevated levels of gallic acid/polyphenol oxidase and methods of generating such plants
发明人：DANDEKAR ABHAYA; MUIR RYANN M

摘要:Gallic acid inhibits the synthesis by A. flavus of aflatoxin, a toxic carcinogen that can contaminate crops such as corn, peanuts and walnuts rendering them inedible. The present invention takes advantage of this inhibition to provide various methods and compositions useful for protecting crops from contamination. Gallic acid is also an intermediate in the production of hydrolyzable tannins, which may sequester protein in the rumen, prevent ammonia formation, and allow protein to be more efficiently absorbed in the post-ruminant digestive system. A second gene, polyphenol oxidase (PPO), also from walnut, may act to help sequester protein during ensiling, also protecting and improving nutritional value. The present invention includes non-naturally occurring plants that contain elevated levels of PPO or gallic acid as well as various methods of generating such plants. The present invention further provides methods of application of gallic acid to prevent contamination. In addition, the present invention provides certain genes and proteins that are be useful in making the non-naturally occurring plants.
