Abstract: Oxazolidinones and methods for their synthesis are provided. Also provided are combinatorial libraries comprising oxazolidinones, and methods to prepare the libraries. Further provided are methods of making biologically active oxazolidinones as well as pharmaceutically acceptable compositions comprising the oxazolidinones. The methods of library preparation include the attachment of oxazolidinones to a solid support. The methods of compound preparation in one embodiment involve the reaction of an iminophosphorane with a carbonyl containing polymeric support.

Abstract: Novel compounds are provided having the formula and salt thereof, where R1 is hydrogen, an alkyl, aralkyl, hydroxymethyl, carboxymethyl acyloxymethyl or trialkylsilyl group, or a group —CH2NR3R4 where N is a linking nitrogen atom and where (a) R3 and R4 are independently selected from hydrogen and alkyl, alkenyl, hydroxyalkyl and alkoxyalkyl groups; (b) R3 is hydrogen or an alkyl, alkenyl, hydroxyalkyl or alkoxyalkyl group, and R4 is —COR5 where R5 is hydrogen or an alkyl, alkenyl, hydroxyalkyl or alkoxyalkyl group; or (c) R3 and R4 taken together with the linking nitrogen atom form a saturated 3- to 7-member heterocyclic group. These compounds are useful intermediates in a process to prepare camptothecin derivatives including the anti-cancer drug irinotecan.
