The present invention features compounds that are prodrugs of HIV integrase inhibitors and therefore are useful in the delivery of compounds for the inhibition of HIV replication, the prevention and/or treatment of infection by HIV, and in the treatment of AIDS and/or ARC.
The present invention features a process for the preparation of 4-oxo-3-[(phenylmethyl)oxy]-4-H-pyran-2-carboxylic acid, an intermediate useful in the synthesis of HIV integrase inhibitors. The process involves (a) treating a compound of formula P-2 with lithium bis(trimethylsilyl)amide and benzaldehyde to form a compound of formula P-3, (b) treating the compound of formula P-3 with triethylamine and methanesulfonyl chloride followed by N-methyl-2-pyrrolidone and 1,8-diazabicyclo[5.4.0]undec-7-ene to form a compound of formula P-4, and (c) treating the compound of formula P-4 with RuCl3 and NaIO4 to form the compound of formula P-5.
Herein described are compounds that are prodrugs of HIV integrase inhibitors and therefore are useful in the delivery of compounds for the inhibition of HIV replication, the prevention and/or treatment of infection by HIV, and in the treatment of AIDS and/or ARC. The present invention features synthetic intermediates and their prepartion.
