合成路线1
该中间体在本合成路线中的序号：(XX)Protection of the free hydroxyl of (XVIII) as the allyloxycarbonyl derivative (XIX) was achieved by sequential treatment with phosgene and then with allyl alcohol. Acetonide group hydrolysis in (XIX) under acidic conditions gave diol (XX), which was selectively silylated at the primary hydroxyl group with tert-butyldimethylsilyl chloride and imidazole to afford (XXI). The remaining hydroxyl group of (XXI) was subsequently protected as the allyl carbonate (XXII) with phosgene and allyl alcohol as above. Then, regioselective mono-desilylation of (XXII) with HF provided the desired building block (XXIII).
