, p. 1729 - 1731 (2000)

A series of 3,3-disubstituted quinoxalinones was prepared and evaluated as HIV-1 reverse transcriptase inhibitors. The N-allyl (6b and 6f), N-cyclopropylmethyl (6a, 6g, 6h and 6k) and N-carboalkoxy (6m-6y) substituted compounds displayed activity comparable or better than Efavirenz and GW420867X.
