The stereoselective synthesis of enantiomerically pure (5R)- and (5S)-aminomethyl-oxazolidinones with different protecting groups have been carried out from an allyl amine as the source of the carbon backbone. The key reaction is the high yield iodiocyclization of enantiomerically pure allylphenethyl amine in the presence of carbon dioxide.

, (2008/06/13)
Disclosed is a process for preparing an optically active oxazolidinone derivative comprising allowing hydrazine to react on an optically active ester having a hydroxyl group at the 3-position which is represented by formula (II): wherein R1represents a lower alkyl group having 1 to 4 carbon atoms, a phenyl group, a methoxymethyl group, a benzyloxymethyl group, a benzyloxycarbonylaminomethyl group which may have a substituent or substituents on the benzene ring thereof, an acylaminomethyl group having 3 to 10 carbon atoms, or an alkyloxycarbonylaminomethyl group having 3 to 6 carbon atoms; R2and R3, which may be the same or different, each represent a hydrogen atom, a lower alkyl group having 1 to 4 carbon atoms, a phenyl group, an acetylaminomethyl group, a benzoylaminomethyl group, or a benzyl group; and * indicates an asymmetric carbon atom, and subjecting the resulting hydrazide to Curtius rearrangement.

An efficient method for the solution phase synthesis of cyclic guanidines is presented. A variety of 2-substituted monoprotected propanediamines react with a set of 5-substituted 2-methylthio-3,4,5,6- tetrahydropyrimidines under Rathke conditions for the construction of a potential library of 81 cyclic guanidines.
Lipophilic Propanediamines: New Building Blocks for Combinatorial Chemistry

, p. 6178 - 6180 (2007/10/03)
Combinatorial chemists need building block libraries where molecular diversity is taken into account.For this purpose, we describe the synthesis of a library of 2-alkyl and 2-alkoxypropanediamines for which a large scale of lipophilicity is investigated.
