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.

权利人:SELEX SENSORS & AIRBORNE SYS
摘要:A cationic oligomer of a saccharide, wherein the saccharide is functionalized by a cationic group, for example an ammonium, phosphonium, imidazolium, or pyridinium group. In a preferred embodiment, the cationic oligomer of a saccharide is a cationic cyclodextrin. There is also provided a use of the cationic oligomer of a saccharide as a chiral agent for resolving enantiomers by a chromatographic method or an asymmetric synthesis.

标 题:Metal oxide-based biocompatible hybrid sorbent for the extraction and enrichment of catecholamine neurotransmitters and related compounds, and method of synthesis
发明人：MALIK ABDUL; ALHENDAL ABDULLAH AWADH
权利人:UNIV SOUTH FLORIDA
摘要:The subject invention concerns metal or metalloid oxide-based sol-gel hybrid sorbent and methods of synthesis. In one embodiment, the sorbent is a ZrO 2 polypropylene oxide based sol-gel. The subject invention also concerns a hollow tube or capillary internally coated with a sorbent of the invention. Sorbent coated tubes and capillaries of the invention can be used in extraction and/or enrichment of samples to be analyzed for catecholamines and related compounds.
