Reducing Agent Bis(trimethylsilyl) has recently been reported to reduce selectively aromatic and heteroaromatic azides to amines in mild conditions (eq 6). Application to the synthesis of benzodiazepine antibiotics is reported. ... 

Applications APCI-MS is often more widely applicable than ESI-MS to the analysis of classes of compounds with a low molecular weight, such as basic drugs and their metabolites, antibiotics, steroids, oestrogens, benzodiazepines, pesticides, surfactants, and most other organic compounds amenable to El. LC-APCI-MS has been used to analyse PET extracts obtained by a disso-lution/precipitation procedure [147]. Other applications of hyphenated APCI mass spectrometric techniques are described elsewhere LC-APCI-MS (Section 7.33.2) and packed column SFC-APCI-MS (Section 73.2.2) for polar nonvolatile organics. 

The carbinolamine-containing pyrrolo[2,l-c][l,4]benzodiazepine family of antitumor antibiotics is produced by various Streptomyces species well-known members include abthramy-cine, tomay mycine, and DC-81,138 Various approaches to the synthesis of these compounds have been investigated over past years reductive cyclization of suitably substituted nitroaldehydes is the frequently used method (Eq. 10.81).139... 

Treatment approaches include (1) reduction of blood ammonia concentrations by dietary restrictions, and drug therapy aimed at inhibiting ammonia production or enhancing its removal (lactulose and antibiotics) and (2) inhibition of y-aminobutyric acid-benzodiazepine receptors by flumazenil.

Ripka et al.[167 168l suggested that benzodiazepines of the type 138 (Scheme 52, experimental details given below) could serve as a mimetic of a (3-turn. This mimetic was incorporated into a cyclic octapeptide -containing analogue of the antibiotic peptide gramicidin S to provide 139 (Scheme 53). 

The C(2)-C(3) olefin of a l,4-benzodiazepin-5-one regiospecifically captured an alkyl radical intramolecularly in a 5-f vo-/r/g-proccss that is the critical step in an approach to the constmction of the fused tricyclic system found in the pyrrolo[2,l-f][l,4]benzodiazepine class of antitumor antibiotic. Treatment of the alkyl bromide 46 with Bu3SnH afforded the tricyclic product 47 in 90% yield, a reaction that proceeded with equal efficiency with the alkoxy aryl ring substituents found in the naturally occurring ( )DC-81 (Scheme 18) <19990L1835>.
