摘要：
The reaction of nitrile imines (II) with alpha-amino esters (III) proceeds with no detectable racemization and constitutes a convenient synthetic route to 4,5-dihydro-1,2,4-triazin-6-ones (IV). Permanganate oxidation of the heterocycles (IV) affords the corresponding 1,2,4-triazin-6-ones (V). The reaction of (II) with beta-amino esters gives the respective acyclic amidrazone adducts (VI).
