Reaction of DAST with secondary alcohols vicinal to an arene Cr(CO) 3 unit gives with very high exo stereoselectivity the corresponding fluorides; the stereochemistry of the reaction appears to be exclusively controlled by the organometallic moiety.

A furo[2,3- c ]pyran-β-D-thymidine nucleoside analog was synthesized from 5′-O-TBDMS-3′-C-allyl-thymidine by 4′-C-hydroxymethylation followed by an electrophilic 6-membered ring annellation. The new bicyclonucleoside was devoid of activity aga
