DI-6R,7R<sup>1</sup>-4(3H)-OXO-2-QUINAZOLINYL-SUBSTITUTED CYCLOBUTANES FROM PINIC AND <i>sym</i>-HOMOPINIC ACIDS
Keywords:
N-acyl derivatives of 5-bromo-, 4-chloro-, and 4,5-dimethoxyanthranilic acids, sym-homopinic acid, di-6,7-substituted 4(3H)-oxo-2-quinazolinyl derivatives of cyclobutane, pinic acidAbstract
The corresponding diamides were obtained from reaction of cis-3-carboxy-2,2-dimethylcyclobutylacetic acid (pinic acid) and of cis/trans-3-(carboxymethyl)-2,2-dimethylcyclobutyl-acetic acid (homopinic acid) dichlorides with two equivalents of 5-bromo-, 4-chloro-, and 4,5-dimethoxyanthranilic acids. Treatment of them with formamide leads to the formation of the corresponding 2,2-dimethyl-3-[4(3H)-oxo-2-quinazolinyl]methyl-1-[4(3H)-oxo-2-quinazolinyl]cyclobutanes and 2,2-dimethyl-1,3-di[4(3H)-oxo-2-quinazolinylmethyl]cyclobutanes.
