Interactions between nitrilimines and the title isocyanide afford, through two competing pathways, 2,3-dihydro-1,2,4-triazines and 1,3-oxazoles. In situ cycloaddition of unreacted nitrilimine with the triazines gives rise to a third class of products, the bicyclic 1,5,6,8a-tetrahydro[1,2...

Syn,syn isomers of oxazolines 3 were selectively achieved by an aldol-like reaction in protic conditions between a-metallated ethyl isocyanoacetate 1 and alpha-acyl alaninates 2. Derivatives 4 with a syn,anti-configuration were obtained under epimerization reaction conditions, whereas derivatives 5-...
An alternative synthesis to this pyrroloquinolone was performed via a reduction of a 2,3,4-trisubstituted pyrrole obtained in turn by treatment of a vinyl sulfone with ethyl isocyanoacetate under basic conditions. A beta-carboline, isomeric with the pyrroloquinolone, was synthesised utilizing a tosyl...
