Item Open Access Intramolecular hetero-Diels-Alder reaction of prolinal-derived N-arylimines : Lewis acid-dependent reversal of the diastereoselectivity(1994) Linkert, Frank; Laschat, SabineIntramolecular Lewis acid-catalyzed hetero-Diels-Alder reaction of L-prolinal-derived N-arylimine 1 yielded diastereoselectively either the cis,cis-azacyclopenta[a]anthracene derivative 2a or the trans,trans-isomer 2b, depending on the Lewis acid.
