TL;DR: In this paper, the Schmidt reaction was used to generate bridged-or fused-bicyclic a-amino carbocations or iminium ions, depending on the geometry about the C(+)-N bond.
Abstract: Aliphatic azides were captured intramolecularlyby carbocations, producing aminodiazonium ion intermediates. Carbon-to-nitrogen rearrangement then occurred, generating bridged- or fused-bicyclic a-amino carbocations or iminium ions, depending on the geometry about the C(+)-N bond. In the bridged systems, rapid elimination of the α-amino carbocations produced twisted enamines with 1-azabicyclo[3.2.2]nonene, 1-azabicyclo[2.2.2]octene, and 1-azabicyclo[3.2.1]octeneskeletons. In the fused systems, the iminium ions were reduced with sodium borohydridetogive 1-azabicyclo [n.3.0]alkanes, where n=4 or 5. The carbocations for these intramolecular Schmidt reactions were generated by treatment of alkenes or alcohols with trifluoromethanesulfonic acid

04 Feb 2010TL;DR: In this paper, the authors proposed novel benzodiazepine derivatives with antiproliferative activity and provided cytotoxic dimers of these compounds, as well as compositions and methods useful for inhibiting abnormal cell growth or treating a proliferative disorder in a mammal.
Abstract: The invention relates to novel benzodiazepine derivatives with antiproliferative activity and more specifically to novel benzodiazepines of formula (I) and (II), in which the diazepine ring (B) is fused with a heterocyclic ring (CD), wherein the heterocyclic ring is bicyclic or a compound of formula (III), in which the diazepine ring (B) is fused with a heterocyclic ring (C), wherein the heterocyclic ring is monocyclic. The invention provides cytotoxic dimers of these compounds. The invention also provides conjugates of the monomers and the dimers. The invention further provides compositions and methods useful for inhibiting abnormal cell growth or treating a proliferative disorder in a mammal using the compounds or conjugates of the invention. The invention further relates to methods of using the compounds or conjugates for in vitro, in situ, and in vivo diagnosis or treatment of mammalian cells, or associated pathological conditions.
