Various functionalized enantiomerically pure 3-hydroxymethyl-1,4-benzoxazine derivatives, including four stereoisomers, were synthesized from chiral 2,3-epoxy-4-trityloxybutanol. The synthesis was mild and metal-free. Yields of 52%–94%, and stereoselectivities of 95% to >99% ee, were obtained. The mechanism was investigated using online Fourier-transform infrared spectroscopy. This revealed a base-promoted

2-Aminobenzoxazoles have been synthesized as ligands for the hepatitis C virus (HCV) internal ribosome entry site (IRES) RNA. The compounds were designed to explore the less basic benzoxazole system as a replacement for the core scaffold in previously discovered benzimidazole viral translation inhibitors. Structure-activity relationships in the target binding of substituted benzoxazole ligands were investigated. (C) 2014 Elsevier Ltd. All rights reserved.
