Improved procedures have been developed for the synthesis of P1 aspartate-based 2,6-dichlorobenzoyloxymethyl ketone 1 and fluoromethyl ketone 2, the prodrugs of two potent ICE-inhibitors. 1 was prepared from (R)-trans-4,5-O-isopropylidene-4,5-dihydroxy-2-pentenecarboxylic acid ethyl ester; 2 was obtained via a nitro-aldol condensation as key step from in situ generated fluoroacetaldehyde. 相似文献

One of the most cited limitations of capillary and microchip electrophoresis is the poor sensitivity. This review continues to update this series of biannual reviews, first published in Electrophoresis in 2007, on developments in the field of online/in‐line concentration methods in capillaries and microchips, covering the period July 2016–June 2018. It includes developments in the field of stacking, covering all methods from field‐amplified sample stacking and large‐volume sample stacking, through to isotachophoresis, dynamic pH junction, and sweeping. Attention is also given to online or in‐line extraction methods that have been used for electrophoresis. 相似文献
