摘要:
The present invention relates to novel nitrification inhibitors of formula I. Moreover, the invention relates to the use of these novel nitrification inhibitors for reducing nitrification, as well as agrochemical mixtures and compositions comprising the nitrification inhibitors. Further encompassed by the present invention are methods for reducing nitrification comprising the treatment of plants, soil and/or loci with said nitrification inhibitors, and methods for treating a fertilizer or a composition by applying said nitrification inhibitor.
摘要:
The present invention relates generally to an eco-friendly methodology for the conversion of alcohols and aldehydes to amines and amides using an integrated enzyme cascade system with metal-and organocatalysis. More specifically, the present invention relates to synthesis of capsaicinoids starting from vanillin alcohol and using a combination of an enzyme cascade system and catalysts. Furthermore, the method also relates to synthesis of capsaicinoids derivatives starting from vanillin alcohol derivatives and using a combination of an enzyme cascade system and catalysts.

摘要:
The synthesis of difluoromethyl ethers and sulfides with a simple, non-ozone- depleting reagent is described. The difluoromethylation of phenols with this reagent occurs at room temperature within minutes with exceptional functional group tolerance. The mild conditions makes possible tandem processes for the conversion of aryl boronic acids, aryl halides and arenes to difluoromethyl ethers. Mechanistic studies support a reaction pathway involving nucleophilic attack of the phenolate to difluorocarbene.
摘要:
Compositions and methods for covalently bonding a polycarboxylic fatty acid and a SERD (selective estrogen receptor degrader) to form fatty acid-drug conjugate compounds are described. The conjugate compounds are useful for increasing solubility of the SERD as well as targeting the SERD to solid tumors. In particular, the compounds are surprisingly efficacious against tamoxifen-resistant tumors. These types of tumors are recalcitrant to existing therapies and often signal the end stage of cancer.
