Synthesis of pyrrolo[2,1-c][1,4]benzodiazepines via reductive cyclization of omega-azido carbonyl compounds by TMSI: An efficient preparation of antibiotic DC-81 and its dimers
A. Kamal et al., Synthesis of pyrrolo[2,1-c][1,4]benzodiazepines via reductive cyclization of omega-azido carbonyl compounds by TMSI: An efficient preparation of antibiotic DC-81 and its dimers, BIOORG MED, 10(20), 2000, pp. 2311-2313
omega -Azido carbonyl compounds on reaction with trimethylsilyl iodide (in
situ prepared from TMSC1/NaI) led to the formation of diazepine imines in g
ood yields under mild conditions. This methodology has been applied to the
parent unsubstituted pyrrolobenzodiazepine, the natural product DC-81 and i
ts dimers. (C) 2000 Elsevier Science Ltd. All rights reserved.
