摘要

Abstract UV light-promoted reduction of acetobromoglucose by NaBH 3 CN in t-BuOH afforded 1, 3, 4, 6-tetra-O-acetyl-2-deoxy-α-d-arabino-hexopyranose in high yield and purity, via a Surzur–Tanner rearrangement, while, with 10 mol% thiophenol added, acetylated 1, 5- anhydro-d-glucitol was cleanly obtained. Such tin-free and mild reductions, presumed to proceed via radical pathways, were more efficient with NaBH 3 CN compared to NaBH 4 ...
