Gitcher SF5 Groups Right Here
I think that several of us in medicinal chemistry have been keeping our eyes out for a chance to work in a pentafluorosulfanyl (SF5) group. I know I have - I actually have a good-sized folder on the things, and some of the intermediates as well, but I've never found the right opportunity. Yeah, I know, they're big and greasy, but since when that that ever stop anyone in this business?
Well, here are are some new routes to (pentafluorosulfanyl)difluoroacetic acid, a compound that had previously only existed in a few scattered literature reports (and those from nasty chemistry). So we all have even less of an excuse to start
polluting enhancing our screening collections with these things. Who's first?
