Synthesis of 7-(β-D-Glucopyranosyl)-6-Thiotheophylline and 7-(α-D-Arabinopyranosyl)-6-Thiotheopwlline. Conformational Study of the Peracetyl Derivatives.
摘要:
The synthesis of two 7-glycosyl-6-thiotheophylline nucleosides where the sugar moieties are beta-D-glucose (1b) and alpha-D-arabinose (2b) is reported. The syn-anti equilibrium of the peracetyl derivatives was studied by the line-shape and the H-1-NMR nOe methods, and molecular mechanics analysis.
