    Enantioselective Diels-Alder reactions are among the most powerful tools in the chemist's toolbox. Over the long history of research into the Diels-Alder reaction, the use of alkynyl ketones and alkynyl esters has been limited. The 1,4-cyclohexadiene products are useful intermediates for the …

  8. Spontaneity to serendipity: from an enediyne core biosynthetic hypothesis to the hexadehydro-Diels-Alder reaction

    … This process, which we have termed a hexadehydro-Diels-Alder (HDDA) reaction, has remained almost entirely unexploited until now. The strategy unites an entirely atom-economical, thermal generation of arynes with their in situ elaboration into a diverse set of polysubstituted benzenoids. HDDA …

The HDDA reaction is a mode of the Diels-Alder reaction that involves [4+2] cycloaddition between a diyne and an alkyne to form aryne reactive intermediate. In Part II we show the scope of substrates that are capable of …
