New carbocyclic adenosine analogues substituted at the 6'-position with fluorine, hydroxyl, methylene, or hydroxymethyl have been synthesized as potential mechanism-based inhibitors of S-adenosylhomocysteine (AdoHcy) hydrolase. The synthetic routes began with a functionalized (+/-)-azidocyclopentane 2, which was elaborated to the adenosine analogue, or with functionalized cyclopentane epoxides 11, 20, and 27, which were opened directly with adenine in the presence of base. The 6' alpha-fluoro, 6' beta-fluoro, and 6'-methylene carbocyclic adenosine analogues were potent inhibitors of AdoHcy hydrolase. None of the compounds displayed significant activity against herpes simplex virus type 1 or type 2, but several demonstrated potent inhibition of vaccinia virus replication.

Bromocyclopentitols and amino (or amido) bromocyclopentitols having a C-Br bond trans to two different vicinal hydroxyl groups show selectivity in base-promoted epoxide formation. The role of adjacent polar substituents in directing bromohydrin cyclization is discussed. (C) 1998 Elsevier Science Ltd. All rights reserved.
