In 1961 Roberts submitted a comprehensive review in which he described the 16 naturally
occurring xanthones identified to that date, of which 5 were of fungal or lichenoid origin. 2 …

Multidrug drug resistant bacteria are becoming increasingly problematic particularly in the
under developed countries of the world. The most important microorganisms that have seen …

Background: Quantum mechanical simulations of chiroptical properties, such as electronic
circular dichroism (ECD), optical rotation (OR), and vibrational circular dichroism (VCD) …

The ProPhenol ligand is a member of the chiral aza‐crown family that spontaneously forms
a bimetallic complex upon treatment with alkyl metal reagents, such as Et2Zn and Bu2Mg …

An enantioselective intramolecular allylic C–H oxidation to generate optically active
chromans has been accomplished under the cooperative catalysis of a palladium complex …

An endophyte is a microbe that lives inside the host plants for part of its life but does not
cause any kind of disease or infection. Plants are continuously faced with a wide range of …

We report the first enantio-and diastereoselective 1, 4-addition of butenolides to chromones.
Both α, β-and β, γ-butenolide nucleophiles are compatible with the Zn-ProPhenol catalyst …

Endophytic fungi are known to harbour compound (s) beneficial for plant health as well as
human health. Among the metabolites of agrochemical and pharmaceutical importance …

Chiral chromanone lactones are a class of natural products with important biological activity.
We report a direct diastereo-and enantioselective vinylogous conjugate addition of …

The first catalytic enantioselective alkynylation of chromones is reported. In this process,
chromones are silylated to form silyloxybenzopyrylium ions that lead to silyl enol ethers after …
