PURPOSE: To prepare the compound useful as an antiviral agent by allowing a specific racemic compound to successively react with an alkali, a chiral primary amine, a nitrosylating agent, a reducing agent, an acid catalyst, a sulfonylating agent and guanine. CONSTITUTION: This preparation comprises: allowing a racemic compound represented by the formula I (wherein each of R 1 and R 2 is a lower alkyl group) to react with an alkali; allowing the reaction product to react with a chiral primary amine represented by the formula R 3NH 2 (wherein R 3 is a (substituted) alkyl group) in the presence of a coupling agent, to obtain a diastereomer mixture; after separating the mixture and protecting its OH groups, allowing the resulting mixture to react with a nitrosylating agent to obtain a compound represented by the formula II (wherein R 3a is a group for protecting the group R 3); treating the compound represented by the formula II with a reducing agent to allow the protecting groups to react with the agent; allowing the treated compound to react with an acid catalyst to obtain a compound represented by the formula III (wherein R 4 is a protecting group); allowing the compound represented by the formula III to react with a sulfonylating agent; then, allowing the sulfonylated compound to further react with (protected) guanine; and thereafter, removing the protected group of the reaction product thus obtained, to prepare the objective optically active compound represented by the formula IV, i.e., (1R(1α,2β,3α))-2- amino-9-(2,3-bis(hydroxymethyl)cyclobutyl)-6H-purin-6-one.

12 SOLUBLE DIAZOALKANE PRECURSORS PCT/GB2007003713 2007-10-01 WO2008040947A3 2008-07-31 MOODY DAVID
The present invention relates to compounds useful in the preparation of diazoalkanes in general (such as diazomethane, diazoethane, diazopropane, diazobutane and homologues) and to diazomethane (CH2=N=N) in particular. The compounds chosen as the diazomethane source according to the invention also have the advantage of being water soluble. They are capable of being decomposed to diazomethane or another diazoalkane (which is allowed to bubble out of the vessel to another vessel containing a solution of reactant) and are converted to by-products that are also water-soluble.
