Compounds 13 & 14 were synthesised from 8 in 4 steps: the 3′-OH/5′-OH TIPS protection of 8 using dichlorotetraisopropylsiloxane in pyridine, followed by oxidation of the 2′ hydroxyl group to the ketone using Moffatt conditions (DCC/orthophosphoric acid in DMSO), reaction with methylmagnesium iodide in diethyl ether and separation of the diastereomeric mixture of tertiary alcohols and finally deprotection using potassium fluoride dihydrate/18-crown-6 in THF
