标 题:Methods and compositions for terpenoid synthesis
发明人：GRENNING ALEXANDER JAMES
权利人:UNIV FLORIDA
摘要:In one aspect, the disclosure relates to methods for preparation of terpene and terpene-like molecules. In a further aspect, the disclosure relates to the products of the disclosed methods, i.e., terpene and terpene-like molecules prepared using the disclosed methods. Intermediates for the synthesis of a wide variety of terpenoids are γ-allyl Knoevenagel adducts or quasi γ-allyl Knoevenagel adducts are disclosed. In various aspects, methods of preparing terpenoids through these intermediates are disclosed. The methods can comprise α-alkylation of an allylic electrophile followed by ring-closure metathesis to a polycyclic terpenoid structure. In a further aspect, the disclosure pertains to terpenoid frameworks, and compounds prepared via disclosed oxidation and substitution reactions on the disclosed terpenoid frameworks. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

摘要:A highly sensitive technology enabling selective recognition of aflatoxins such as in contaminated cereal samples. Methods for the synthesis of AgNP-containing MIP membranes from the monomer mixtures containing both methacrylate monomers and oligomers as well as AgNOs solution in dimethylformamide enable the detection system. The AgNP were formed in the structure of the polymeric membranes during the pre-heating step followed by the UV-initiated polymerization. The highly selective sensor elements where MIP membranes are combined with the Ag nanostructures as signal amplifiers (LSPR-MIP nanochips) can be stored separately and used with a simple optical recognition system as selective elements of point-of-care sensor devices, even in in-field conditions. Composite plasmonic membranes provide both highly selective recognition of the target toxin and the generation of an enhanced optical signal, allowing aflatoxin B1 detection at ultralow concentrations.
