It is widely recognized that Diels-Alder reactions are the most useful pericyclic reactions for
the construction of six-membered functionalized carbocyclic compounds. The potency of …

Spirans contain at least two rings, which share one carbon atom called the spirocarbon
atom. 1 Synthetic and natural spirocarbocycles attract the attention of organic chemists due …

The chemistry of aromatics traditionally centers on use of electrophilic and nucleophilic
substitutions. This is largely because strategies based on such concepts are well …

There are numerous examples of biologically active natural products that possess a
naphthalene or naphthoquinone core. 1 Nanaomycin A 1, for example, a member of the …

The reactions of cyclic anhydrides acting dually as acylating agents and C-nucleophiles in
stereoselective annulation reactions provide efficient one-step synthesis of polysubstituted …

A novel sulfenylation method induced by aromatization of quinone mono-O, S-acetals is
described. These sulfenylation reagents readily react with silyl enolethers or electron rich …

An organocatalytic enantioselective Tamura cycloaddition between homophthalic
anhydrides and 2-arylidene-1, 3-indanediones has been developed. With 2 mol% of …

The first examples of asymmetric Tamura cycloaddition reactions involving singly activated
alkenes are reported. Homophthalic anhydride reacts with α-methyl nitrosytrenes in the …

In the presence of carbon tetrabromide, a variety of dithiocarbamates, xanthates,
dithioesters, and thioethers were prepared in one pot by reacting the corresponding dithioic …
