W. Kantlehner et M. Hauber, ORTHOAMIDES .48. REACTIONS OF AN AZAVINYLOGUE AMINALESTER [2-AZA-1,3-BIS(DIMETHYLAMINO)3-METHOXY-1-PROPEN] WITH CH2-ACIDIC COMPOUNDS, Bulletin des Societes chimiques belges, 103(12), 1994, pp. 697-703
Condensation reactions of azavinylogue orthoamides 5a and 69 with CH2-
acidic compounds are described. Reaction products are formylated - or
azavinylogue formylated compounds 8 and 9 resp. The condensation react
ions of 5a can be enhanced by addition of trimethyl berate. Under thes
e conditions the formylations reaction-leading to compounds of type 8
- is preferred.
