A new approach to morpholin-2-one derivatives via the reaction of β-amino alcohols with dicyanofumarates


Mloston, G; Pieczonka, A M; Korany, A A; Linden, A; Heimgartner, H (2012). A new approach to morpholin-2-one derivatives via the reaction of β-amino alcohols with dicyanofumarates. ARKIVOC, 2012(iii):181-192.

Abstract

A novel approach for the synthesis of morpholin-2-one derivatives from dialkyl dicyanofumarates and β-amino alcohols is presented. The reaction takes place under mild conditions via an addition-elimination-lactonization pathway. The formation of the six- membered ring occurs selectively leading to a single diastereomer. In contrast to arylhydrazines, the reaction of hydrazine hydrate with dicyanofumarates yields pyrazol-3(2H)-ones and not 5-aminopyrazoles.
