An easy access to spiroannulated glyco-oxetane, -thietane and -azetane rings: synthesis of spironucleosides
摘要:
The key intermediate 11 derived from D-glucose and possessing bis-mesylmethyl (MsO center dot CH2-) functionality at C-4, was used to generate spirocycles 12, 13 and 15 via one-step procedures. The spirocompounds 12 and 13 were subsequently converted into the corresponding spironucleosides 24 and 26 in good yield using Vorbruggen reaction conditions. (c) 2006 Elsevier Ltd.
