The invention relates to a novel process for the preparation of an aminoalcohol of the formula
racemically or optically active, starting from 2-azabicyclo[2.2.1]hept-5-en-3-one, its further conversion to give the corresponding acyl derivative and its further conversion to (1S,4R)- or (1R,4S)-4-(2-amino-6-chloro-9-H-purine-9-yl)-2-cyclopentenyl-1-methanol of the formulae
In the latter synthesis, the aminoalcohol is converted into the corresponding D- or L-tartrate, which is then reacted with N-(2-amino-4,6-dichloropyrimidin-5-yl)formamide of the formula
to give (1S,4R)- or (1R,4S)-4-[(2-amino-6-chloro-5-formamido-4-pyrimidinyl)amino]-2-cyclopentenyl-1-methanol of the formulae
and then cyclized to give the end compounds.
本发明涉及一种新的制备式为2-azabicyclo[2.2.1]庚-5-烯-3-酮的氨基醇的方法,该氨基醇可以是外消旋或光学活性的,进一步转化为相应的酰基衍生物,然后进一步转化为式为(1S,4R)-或(1R,4S)-4-(2-氨基-6-氯-9-H-嘌呤-9-基)-2-环戊烯基-1-甲醇的化合物。在后一种合成中,氨基醇被转化为相应的D-或L-酒石酸盐,然后与式为N-(2-氨基-4,6-二氯嘧啶-5-基)甲酰胺的化合物反应,得到式为(1S,4R)-或(1R,4S)-4-[(2-氨基-6-氯-5-甲酰胺基-4-嘧啶基)氨基]-2-环戊烯基-1-甲醇的化合物,然后环化得到最终产物。
