Synthesis of a Base-Protected α-L-LNA Guanine Nucleoside
摘要:
Synthesis of (1R,3R,4S,7R)-7-hydroxy-1-hydroxymethyl-3-(2-N-isobutyroylguanin-9-yl)-2,5-dioxabicyclo[2.2.1]heptane (12), a protected alpha-L-LNA guanine nucleoside, has been accomplished using a convergent synthetic strategy starting from 1,2-di-O-acetylfuranose 4.
