β¦ Synopsis
A recyclable fluorous labeled THP protecting group has been developed that allows for simple purification of small molecules by liquid-liquid extraction with FC-72/MeCN, and of larger or more polar molecules by solid phase extraction with fluorous reverse phase silica gel. In addition, we report a new glycosylation method which uses the Cp,ZrCI,-AgCIO, reagent system to activate an anomeric sulfoxide.
