A new class of pyrazolone-fused 3-amino-1,3,4,7-tetrahydro-2H-azepin-2-ones was synthesized from azepane-based α,β-unsaturated esters. The latter compounds were obtained efficiently from 2-Cbz-amino-N-(2-bromoallyl)-4-pentenamide derivatives through initi

Gram-negative bacteria often use N-acyl-homoserine lactones (AHLs) as signal molecules to monitor their local population densities and to regulate gene-expression in a process called "Quorum Sensing" (QS). This cell-to-cell communication allows bacteria to adapt to environmental changes and to behave as multicellular communities. QS plays a key role in both bacterial virulence towards the host and symbiotic interactions with other organisms. Plants also perceive AHLs and respond to them with changes in gene expression or modifications in development. Herein, we report the synthesis of new AHL-derivatives for the investigation and identification of AHL-interacting proteins. We show that our new compounds are still recognised by different bacteria and that a novel biotin-tagged-AHL derivative interacts with a bacterial AHL receptor.
Resolution of non-proteinogenic amino acids via microbial lipase-catalyzed enantioselective transesterification
Miyazawa, Toshifumi,Mio, Motoe,Watanabe, Yuko,Yamada, Takashi

A number of non-proteinogenic amino acids bearing aliphatic side chains were resolved with moderate to good enantioselectivities (E = 15-42) through the Burkholderia cepacia lipase-catalyzed enantioselective transesterification of the 2,2,2-trifluoroethyl esters of their N-benzyloxycarbonyl derivatives with methanol as a nucleophile in diisopropyl ether.
