Fluorophores derived from photoactivatable azide-pi-acceptor fluorogens or from a thermal reaction of an azide-pi-acceptor fluorogen with an alkene or alkyne are disclosed. Fluorophores derived from a thermal reaction of an alkyne-pi-acceptor fluorogen with an azide are also disclosed. The fluorophores can readily be activated by light and can be used to label a biomolecule and imaged on a single-molecule level in living cells.
The present disclosure relates to compounds, compositions and methods for the treatment of Hepatitis C virus (HCV) infection. Also disclosed are pharmaceutical compositions containing such compounds and methods for using these compounds in the treatment of HCV infection.

meso-Spirodiol 12 and spirodiacetate 13 were stereoselectively prepared using pi-face selective Grignard addition to norbornanone 7. Asymmetric transesterification of meso-diol and hydrolysis of meso-diacetate were studied using lipases. Pseudomonas fluorescens lipase-catalyzed transesterification of meso-diol 12 afforded the monoacetate (-)-21 of high enantiomeric excess (>99% ee). The formal synthesis of(-)-curcumanolide A has been achieved from the optically active (-)-21.
