ACID-CATALYZED CYCLIZATION OF 2-HYDROXY-3-PYRROLONE DERIVATIVES. 2-METHOXY-3(2H)-FURANONES AS PRECURSORS OF POLYCYCLIC NITROGEN HETEROCYCLES

Freeman, Jeremiah P.,Fettes-Fields, Mary Kay

, p. 1073 - 1076 (2007/10/02)

Condensation of 2-methoxy-3(2H)-furanones with β-substituted ethylamines followed by treatment with various acid catalysts gives rise to polycyclic nitrogen heterocycles by way of two intramolecular cyclizations.The pathway depends upon the nature of the
