[4+2] cycloadditions of iminoacetonitriles : a general strategy for the synthesis of quinolizidines, indolizidines, and piperidines
… Diels-Alder cycloadditions leading to quinolizidines, indolizidines, and piperidines. The resultant a-amino nitrile cycloadducts are versatile synthetic intermediates which can be further elaborated by stereoselective alkylation, reduction, reductive cyclization, and Bruylants …

Enantioselective [4 + 2] cycloadditions of iminoacetonitriles : application to the total synthesis of (-)-quinolizidine 2071
… Diels-Alder cycloadditions affording quinolizidines and indolizidines. The resulting a-amino nitrile cycloadducts are versatile intermediates that can be further elaborated in a stereoselective manner. This thesis describes the development of intramolecular, enantioselective aza Diels- …

Synthesis of nitrogen heterocycles via the intramolecular [4+2] cycloaddition of iminoacetonitriles
… Diels-Alder reactions, affording substituted quinolizidines and indolizidines. The cycloadducts are formed with a high preference for an exo-orientated cyano group due to the a-amino nitrile anomeric effect. The substrates for these [4+2] cycloadditions are prepared from readily available …
