摘要:
N-2-Acetyl-8-bromoguanine has been found to react readily with 2,3-dihydrofuran in DMF in the presence of acid catalyst at room temperature to give 9-(tetrahydrofuryl-2)-8-bromo-N-2-acetylguanine in high yield. The structures of this compound and its deacetylated derivative were assigned by H-1 and C-13 NMR spectroscopy.
