coupling constants of 1 H-n.m.r. spectra of the perbenzoates of α- d -glucopyranose ( 1 ), β- d -glucopyranose ( 2 ), α- d -galactopyranose ( 3 ), α- d -mannopyranose ( 4 ), β- d -mannopyranose ( 5 ), and α- d -galactofuranose ( 6 ) are reported. The 13 C-n.m.r. chemical shifts of compounds 1-3 and 6 , and of penta- O -benzoyl-β- d -galactofuranose ( 7 ) are given. Mass spectra were used to differentiate
摘要α-d-吡喃葡萄糖(1),β-d-吡喃葡萄糖(2),α-d-吡喃半乳糖(3),α-d-甘露吡喃糖(4)的过苯甲酸酯的1 Hn.mr光谱的化学位移和耦合常数),β-d-甘露吡喃糖(5)和α-d-半乳糖呋喃糖(6)的报道。给出了化合物1-3和6以及五-O-苯甲酰基-β-d-半乳糖呋喃糖的13 Cn.mr化学位移。质谱用于将呋喃糖酶6和7与吡喃糖3区别开。
