A novel synthesis of 2-substituted 2H-imidazo[1,5-b]isoquinoline-1,5-diones by in situ desulfurization
摘要:
A novel synthesis of 2-substituted 2H-imidazo[1,5-b]isoquinoline-1,5-diones by reductive desulfurization of a variety of 2-substituted 3-thioxo-2H-imidazo[1,5-b]isoquinoline-1,5-diones is reported with nickel boride in dry methanol at ambient temperature.
