Biosynthesis of oxygen and nitrogen-containing heterocycles in polyketides
This review highlights the biosynthesis of heterocycles in polyketide natural products with a focus on oxygen and nitrogen-containing heterocycles with ring sizes between 3 and 6 atoms. Heterocycles are abundant structural elements of natural products from all classes and they often contribute significantly to their biological activity. Progress in recent years has led to a much better understa...
متن کاملConstruction of nitrogen-containing heterocycles by C-H bond functionalization.
Nitrogen heterocycles are abundant in natural products and pharmaceuticals. An emerging interest among synthetic chemists is to use C-H functionalization to construct the nitrogen-containing core of these heterocycles. The following article will provide a brief overview of this concept with respect to the type of C-H bond functionalized.
متن کاملPolyethylene glycol embedded tribromide as an efficient and reusable catalyst for the library synthesis of nitrogen containing heterocycles
Potassium tribromide wrapped around polyethylene glycol ({K+PEG400}Br3-) was easily prepared by two step reaction of PEG400 with KBr followed by the addition of molecular bromine to give PEG embedded potassium tribromide as a dark viscous oil. The synthesized material was found to be an efficient, cost effective, environmentally benig...
متن کاملFactors influencing the selectivity in asymmetric oxidation of sulfides attached to nitrogen containing heterocycles.
Asymmetric oxidation of heterocyclic sulfides, including imidazole, benzimidazole, indole and pyrimidine derivatives, were studied using a tartrate/Ti((i)OPr)4 catalyst system.
متن کاملSynthesis and Antibacterial and Antifungal Studies of Novel Nitrogen Containing Heterocycles from 5-Ethylpyridin-2-ethanol
A novel series of chalcones, pyrimidines and imidazolinone is described; chalcones (4a-o) were prepared from the lead molecule 4-[2-(5-ethylpyridin-2-yl)ethoxy]benzaldehyde. Pyrimidine (5a-o) derivatives were prepared from the reaction of chalcones and guanidine nitrate in alkali media. Imidazolinones (6a-o) were synthesized from reaction of pyrimidine and oxazolone derivatives (prepared by Erl...
