followed by catalytic hydrogenation and deprotection, gave the corresponding 1- C -(α- d -arabinofuranosyl)methylamine. Reductive amination of ethyl 2,3- O -isopropylidene-α- d - lyxo -pentodialdo-1,4-furanoside using aniline gave ethyl 5-anilino-5-deoxy- d - lyxo -furanoside. Inhibition studies with these compounds on β- d -glucosidase from sweet almond, using o -nitrophenyl d -glucopyranoside as substrate
摘要由C-葡吡喃糖基丙烯前体经臭氧分解制备了C-葡糖醛,2-C-(2,3,4,6-四-O-乙酰基-α-d-吡喃吡喃糖基)乙醛。C-葡萄糖基醛的还原胺化和随后的脱保护得到1-苯胺基-2-C-(α-d-吡喃葡萄糖基)乙烷。通过用羟胺处理其醛前体来制备肟衍生物1-C-(α-d-阿拉伯呋喃糖基)甲氧基肟的E和Z异构体。肟的乙酰化,然后催化氢化和脱保护,得到相应的1-C-(α-d-阿拉伯呋喃糖基)甲胺。用苯胺将2,3-O-异亚丙基-α-d-lyxo-戊二醛-1,4-呋喃糖苷还原胺化,得到5-苯胺基-5-脱氧-d-lyxo-呋喃糖苷乙基。这些化合物对甜杏仁中β-d-葡萄糖苷酶的抑制作用研究,
