Novel 1,4-Benzodiazepines from Acylnitroso-Derived Hetero-Diels−Alder Cycloadducts
摘要:
GRAPHICSN-4-Hydroxy-1,4-benzodiazepines were synthesized in a single step from synthetically versatile acyinitroso-derived hetero-Diels-Alder cycloadducts. The efficiency of this transformation was found to be dependent on the NH pK(a) of the cycloadduct sulfonamide.
