The following examples report the published orientation, but the reader will keep in mind the possibility of isomerization. Methyl dimethylaminopro-piolate (Me2NC=CC02Me) and ethyl azidoformate, stirred in tetrahydro-furan, gave 4-dimethylamino-3-ethoxycarbonyl-5-methoxycarbonyltriazole (25°C, 3 hr, 70%). l-Dimethylaminobut-l-yn-3-one similarly gave 5-acetyl-4-dimethylamino-3-ethoxycarbonyltriazole (80%) (69HCA2641).

Formylation of dimethyl 1 -(methoxycarbonyl)methylphosphonate with methyl formate under basic conditions using MeONa/MeOH results in the quantitative formation of the sodium enolate. An alternative procedure is the preparation of masked aldehydes by reaction of tert-butoxy-Z T(dimethylamino)methane or ATV-dimcIliyllonnarnidc dimethyl acetal with diethyl 1-(ethoxycarbonyl)methylphosphonate. The former reacts at 160°C for 3 h with diethyl l-(ethoxy-carbonyl)methylphosphonate to give the corresponding enaminophosphonate in 72% yield, whereas the use of the latter increases reaction yields (82-95%) and rates (2 The subsequent...
