Mono‐, di‐ und trisubstituierte 2‐Aminonicotinonitrile vom Typ 8, 13, 14 und 19 lassen sich aus Keton‐Mannich‐Basen Hydrochloriden 4 · HCl, Enonen 12, β‐Aminovinylketonen 17, 3‐Aminoacrolein‐Derivaten 18 sowie Vinamidinium Perchloraten 21 und in situ erzeugtem 3,3‐Diamino‐acrylnitril (3) herstellen.
Matrix compare analysis discriminates subtle structural differences in a family of novel antiproliferative agents, diaryl-3-hydroxy-2,3,3a,10a-tetrahydrobenzo[b]cycylopenta[e]azepine-4,10(1H,5H)-diones

A diastereoselective synthesis of diaryl-3-hydroxy-2,3,3a,10a-tetrahydrobenzo[b]cycylopenta[e]azepine-4,10(1H,5H)-diones is described employing a tandem Michael-aldol addition as key step. The novel compounds exhibit antiproliferative activity in a panel of in vitro cultivated cancer cell lines. The bioinformatic tool COMPARE was able to discriminate between two closely related subgroups of the title compounds, namely 1,3- and 2,3-disubstituted derivatives. (C) 2006 Elsevier Ltd.
