Abstract
Dipyrrinones formed by DBU and n-Bu3P-promoted condensation of 5-p-toluene- sulfonylpyrrolinones with pyrrole 2-aldehydes, gave high yields of product with predominantly the E-configuration when the aldehyde had a 5-carboethox y group. The 4E-dipyrrinones were readily purified by chromatography and we re stable in solutions shielded from light. (C) 1999 Elsevier Science Ltd. All rights reserved.
