For the preparation of a carbocyclic nitrogen analogue of S-adenosylmethionine (carba-AdoazaMet, 4), a practical synthesis of (-)-aristeromycin (7) has been developed using variations of literature procedures. This approach called for a stereospecific synthesis of (3aR,6aR)-2,2-dimethyl-3a, 6a-dihydrocyclopenta[1,3]dioxol-4-one ((4R, 5R)-4,5-O-isopropylidene-2-cyclopentenone) (8), which was achieved by modifying reported procedures from D-(-)-ribose.

Moffatt oxidation of 2',3'-O-isopropylidenearisteromycin (1a) and treatment of the 5'-carboxaldehyde with [(p- tolylsulfonyl)methylene]triphenylphosphorane gave the homologated vinylsulfone 2. Treatment of 2 with tributylstannane/AIBN gave the (E/Z)- vinylstannanes which were converted into the E and Z fluoro- and iodovinyl analogs. Chain extension via the 5'-cyano-5'-deoxy derivative 10a gave the 6'-carboxaldehyde of homoaristeromycin. S-Adenosyl-L-homocysteine hydrolase was strongly inhibited by the fluorovinyl, 5b, and iodovinyl, 4b and 7b, compounds, and time-dependent kinetics were observed [1-2 μM (K(i)) and 0.1- 0.2 min-1 (k(inact))]. The mechanism of inactivation was shown to involve addition of water at the vinyl 5' or 6' carbons with elimination of halide.
