The existence of a peroxygen acid of sulfur was recognized nearly one and half centuries
ago, 1, 2 but it was not until 1898 that Caro 3 demonstrated the existence of two such acids …

Dioxiranes can be generated in situ10, 13 from ketones and Oxone (2KHSO5· KHSO4·
K2SO4)(Scheme 1). 14 In principle, only a catalytic amount of ketone should be needed …

The structural features of polycyclic polyether natural products can, in some cases, be traced
to their biosynthetic origin. However in case that are less well understood, only biosynthetic …

Selectivity rules in organic chemistry have been inferred largely from nonaqueous
environments. In contrast, enzymes operate in water, and the chemical effect of the medium …

Six-membered oxygenated heterocycles, or pyrans, are probably one of the most common
structural motifs spread across natural products, from simple glucose to structurally complex …

The trans-fused polycyclic ethers are one of the most characteristic and spectacular classes
of compounds isolated from marine sources. These molecules are produced by marine …

Pnictogen‐bonding catalysis and supramolecular σ‐hole catalysis in general is currently
being introduced as the non‐covalent counterpart of covalent Lewis acid catalysis. With …

As pharmaceutical companies look to develop single enantiomers as drug candidates,
chemists are increasingly faced with the problems associated with this subclass of organic …

The autocatalysis of epoxide-opening ether cyclizations on the aromatic surface of anion− π
catalysts stands out as a leading example of emergent properties expected from the …
