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.

By employing an intramolecular Pd(0)-mediated ring opening of an acylnitroso-derived cycloadduct, newhydroxamicacid containing benzodiazepines have been synthesized and have demonstrated biological activity in MCF-7 and PC-3 tumor cell lines. Subsequent N−O bond reduction of the hydroxamate has provided access to amide analogues for SAR studies. During the course of our syntheses, an intermediate
