摘要

Abstract Reaction of stereoisomeric 8-bromo-9-(2, 3-O-isopropylidene-2, 3, 4- trihydroxybutyl) adenines (8) with concentrated aqueous ammonia, sodium hydride, potassium tert-butoxide, or 1, 8-diazabicyclo [5, 4, 0] undec-7-ene afforded 4e-O, 8-anhydro- 9-(2, 3-O-isopropylidene-2, 3, 4-trihydroxybutyl) adenines 9 (derivatives of 1, 3-oxazepino [2, 3-e] adenine). The CD spectra of optically active stereoisomers of 9 have been studied ...
