<p>3,4-Disubstituted-1-cyclopentene compounds, in substantially enantiopure form, have the relative stereochemistry according to formula (1A) or (1B) including the opposite enantiomers thereof, wherein R1 is either COOX, wherein X is alkyl, H or a salt-forming cation, or CH¿2?OH, wherein the hydroxyl group is optionally protected; R?2¿ is H or a protecting group; R3 is H or alkyl; and R4 is H, alkoxy, alkyl, aryl or aralkyl; or, in the case of formula 1A, R?2 and R4¿ are linked to form an oxazolidinone ring. These compounds can be used to prepare a series of complementary stereochemically varied cyclopentane scaffolds.</p> |
