The first total syntheses of punicafolin (1) and macaranganin (2) were achieved in seven steps, respectively, from commercial α-d-glucose. The characteristic features of the synthesis are (1) sequential site-selective introduction of the adequate ga

Total synthesis of cercidinin A (1) was achieved in 7 overall steps from d-glucose (9 steps from gallic acid) via sequential site-selective introduction of requisite galloyl groups into hydroxy gro...

An SN2 mechanism was proposed for highly stereoselective glycosylation of benzoic acid with unprotected α-d-glucose under Mitsunobu conditions in dioxane, while an SN1 mechanism was indicated for nonstereoselective glycosylation in DMF. The SN2-type

An SN2 mechanism was proposed for highly stereoselective glycosylation of benzoic acid with unprotected α-D-glucose under Mitsunobu conditions in dioxane, while an SN1 mechanism seems to be responsible for non-stereoselective glycosylation in DMF. T

Introduction Several lines of evidence suggest that 7α-substituted estradiol derivatives bind to the estrogen receptor (ER). In line with this hypothesis, we designed and synthesized 18 F-labeled 7α-fluoroalkylestradiol (Cn-7α-[ 18 F]FES) derivati
