Pyrrolo[1,2-a][1,4]benzodiazepine: A novel class of non-azole anti-dermatophyte anti-fungal agents
摘要:
Broad screening revealed compound la to be a novel anti-fungal agent with high specificity towards dermatophytes. The anti-fungal structure-activity relationship of this novel class of 5,6-dihydro-4H-pyrrolo[1,2-a][1,4]benzodiazepines is described together with its mode of action that appeared to be the inhibition of squalene epoxidase. Preliminary in vivo results of the most active compounds are also reported. (c) 2005 Elsevier Ltd. All rights reserved.

A method for the annulation of amines and carboxylicacids to form pharmaceutically relevant azaheterocycles via organophosphorus PIII/PV redox catalysis is reported. The method employs a phosphetane catalyst together with a mild bromenium oxidant and terminal hydrosilane reductant to drive successive C–N and C–C bond-forming dehydration events via the serial action of a catalytic bromophosphonium
