Phase transfer catalyzed asymmetric alkylations of imine glycinamides
摘要:
Herein we report the use of achiral imine glycinamides as substrates for asymmetric alkylations using chiral phase-transfer catalysts for the first time. Initially tried for obtaining a key intermediate for the synthesis of levobupivacaine, we expanded the study to other N-mono and N,N-disubstituted imine glycinamides. A possible explanation for the lower enantioselectivity observed in the ease of alkylation of N-monosubstituted as compared to N,N-disubstituted glycinamides is also provided. (C) 2003 Elsevier Ltd.

(2S)-cyanoPro scaffold as a possible entry to highly potent and selective FAP inhibitors. In the present study, we explore in detail the structure–activityrelationship around this core scaffold. We report extensively optimized compounds that display low nanomolar inhibitory potency and high selectivity against the related dipeptidylpeptidases (DPPs) DPPIV, DPP9, DPPII, and prolyl oligopeptidase (PREP)
The present invention relates to benzonaphthyridinamines of the formula (I) as autotaxin inhibitors and to the use thereof in the treatment and/or prophylaxis of physiological and/or pathophysiological conditions in which the inhibition, regulation and/or modulation of phosphodiesterase or lysophospholipase autotaxin plays a role, in particular of various types of cancer and autoimmune and inflammatory diseases.

ruthenium(II) complexes are reported. Five of these were characterised by X‐ray crystallography. The activities of this collection of catalysts were initially compared for the hydrogenation of two model ester hydrogenations. Catalyst turnover frequencies up to 2400 h−1 were observed at 85 °C. However, turnover is slow at near ambient temperatures. By using a phosphine‐diamine RuII complex, identified
