One Pot Synthesis

A convenient two-step, one-pot synthesis of 4-chloro-2-(trichloromethyl)pyrimidines starting from 2-(trichloromethyl)-1,3-diazabutadienes is described. These nitrogen heterocycles were prepared by a sequential acylation/intramolecular cyclization reaction between 2-(trichloromethyl)-1,3-diazabutadienes and acyl chlorides in the presence of triethylamine followed by treatment with POCl3. This is the first report for the synthesis of this type of 4-chloro-2-(trichloromethyl)pyrimidine derivatives and serves as a source for a wide variety of other substituted pyrimidines by nucleophilic substitution reactions.

Metal-free cascade cyclization of 2-acylbenzoic acids with amines provided a one-pot synthesis of diverse isoindoloisoquinoline and benzoindolizinoindole derivatives, which were subsequently used to produce nitrogen-containing nine-membered ring compounds.
