The application of alkyl and aryl substituted cyanamides in synthetic chemistry has diversified multi-fold in recent years. In this review, we discuss recent advances (since 2012) in the chemistry of cyanamides and detail their application in cycloaddition chemistry, aminocyanation reactions, as well as electrophilic cyanide-transfer agents and their unique radical and coordination chemistry.

An unprecedented intermolecular cyclizative capture of the cyanamide anion and several nitrile oxides enables the synthesis of oxadiazol-5-imines.

The biomimetic synthesis and structural reassignment of tridachiahydropyrone, tridachiahydropyrone B and tridachiahydropyrone C, isolated from mollusks of the order Sacoglossa, using a sequence of photochemical transformations from a common polyene precursor are described. These complex natural products may act as sunscreens for the producing organism, thus offering protection from harmful UV radiation and oxidative damage.
