Article abstract of DOI:10.1007/BF00900767

Trimethyl orthoacetate, orthopropionate or orthobenzoate in contrast to orthoformiate do not undergo a three component condensation with anilines and cyclic sixmembered active methylene compounds to the corresponding N-substituted aminomethylene derivativ
