A comparison between the pressure effects on the catalysis of Thermoanaerobium brockii alcohol dehydrogenase (TBADH: a thermostable tetrameric enzyme) and yeast alcohol dehydrogenase (YADH: a mesostable tetrameric enzyme) revealed a different behaviour. YADH activity is continuously inhibited by an increase

[reaction: see text] Enzymatic resolution of Boc-protected 4-aminocyclopenten-1-ol 4c gave both enantiomers 5c and 6c in high ee. Boc removal and separate condensation with chloropyrazolopyrimidine 18 provided elaborated 1,4-aminocyclopentenol derivatives 20 and 26, respectively. Separate treatment of 20 and 26

Bicyclic cyclopentane lactones, prepared from bromodeoxyaldonolactones, were transformed into aminocyclopentanols with an Overman rearrangement as the key step. Two of the compounds prepared, 7 and 19, were found to be good inhibitors of jack bean alpha-mannosidase and beta-D-N-acetylglucosaminidase, respectively.
