Contribution to the total synthesis of caribenolide I

The C13-C29 fragment of caribenolide I was prepared with a total control of the configuration of 5 stereogenic centres (out of 6). The key steps rely on the use of a chiral oxazolidin-2-thione for a highly diastereoselective C-glycosylation, and the vinylogous Mukayiama aldol reaction.
