ring is constructed on a molecule. Examples are the Robinson annulation, Danheiser annulation and certain cycloadditions. Annular molecules are constructed...

to do a tandem ring-contraction, and [2 + 2] cycloaddition. The Danheiser benzannulation photolyses α-diazo ketones and traps with an alkyne, which undergoes...

unsaturated precursors include the Dötz reaction, palladium-catalyzed [4+2] benzannulation of enynes with alkynes, and Lewis-acid-mediated [4+2] cycloaddition...
