Usefulness of the Global E Factor as a Tool to Compare Different Catalytic Strategies: Four Case Studies

The global E factor (EG factor) has recently been introduced, in the context of asymmetric organocatalysis, as a new green chemistry metric to take into consideration synthesis catalyst overall economy synthetic process given chiral molecule optically pure form. Herein, its further usefulness comparing diverse catalytic systems, even different from organocatalysts, is shown by analysis four case studies.
