Synthesis of Quinoxaline Macrocycles
2016Macrocyclic compounds are widespread in nature. These are porphyrins (chlorophyll, heme as a part of hemoglobin, Vitamin B12), cyclic peptides (antibiotics gramicidin C, capreomycin, valinomycin, vancomycin, amato, and fallotokcins of death cup amanita (Amanita phalloides) and some toadstools), macrocyclic alkaloids (including tubocurarin–the main ...

Recent Advances in Quinoxaline Chemistry
1963Publisher Summary This chapter outlines the progress in quinoxaline chemistry. The preparation of numerous reduced quinoxalines and more unusual derivatives of this type include quinoxaline spirohydantoins and quinoxaline spiroindoles. Quinoxaline is resistant to nitration under mild conditions.
