utilization of N‐centered radicals to synthesize nitrogen‐containing compounds has attracted considerable attention recently, due to their powerful reactivities and the concomitant construction of C−N bonds. However, the generation and control of N‐centered radicals remain particularly challenging. We report a tethering strategy using SOMO‐HOMO‐converted distonic radical anions for the site‐specific

Described herein are small-molecule mimics of CD4, which both enter the Phe43 cavity and target Asp368 of gpl20, the HIV-1 envelope protein. Also described herein are methods of using these compounds to inhibit the transmission or progression of HIV infection. These compounds exhibit antiviral potency greater than that of a known antiviral, NBD-556, with 100% breadth against clade B and C viruses. Importantly, the compounds do not activate HIV infection of CD4-negative, CCR5-positive cells, in contrast to NBD- 556.
