A very short reaction sequence opens with metal-mediated
addition of commercial bromodifluoropropene to aldehydes; allylation under
phase transfer catalysed conditions sets the stage for a ring closing
metathesis (RCM) in the presence of commercial Grubbs’ catalyst to
afford potentially useful difluorinated dihydropyrans.

direct sequence involving ring-closingmetathesis and indium-mediated difluoroallylation with 1-bromo-1,1-difluoropropene in water. Two protecting group strategies were explored, one to allow protection of the primary C-6 hydroxyl group throughout the sequence, while the second was intended to allow deprotection after RCM and before dihydroxylation. The benzyl ether could be used in the first role, and
