Process for the preparation of aminoalcohol derivatives and their further conversion to (1R, 4S)-4(2-amino-6-chloro-5-formamido-4-pyrimidinyl)-amino-2-cyclopentenyl-1-methanol

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-am...

Beschreibung
Zusammenfassung:	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.
