Stereoselective synthesis of helical dihydrodipyrrolophenanthroline and hindrance hexa tert-butyl carboxylatodipyrrolophenanthroline from reaction between 1,10-phenanthroline and dialkyl acetylenedicarboxylates

摘要

High hindrance Hexa tert-butoxy carbonyl dipyrrolophenanthroline and helical dihydropyrrolophenanthroline compounds were prepared from reactions between di tert-butyl acetylenedicarboxylate and 1,10-phenanthroline in polar solvents media.
