Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are of increasing
importance in the treatment of HIV-1 infected persons. In this review the f
ocus is on the syntheses of the approved NNRTI drugs efavirenz, delavirdine
, nevirapine, and their analogues. This review also deals with the synthese
s of the most promising NNRTI candidates in clinical testing and with the s
yntheses of subclasses of NNRTIs with known crystal structures when complex
ed with the reverse transcriptase enzyme.
