synthetically valuable nitrogen‐containing building blocks which are difficult to obtain with alternative methods. Preliminary mechanisticstudies suggest that the reaction may proceed through a new mechanistic pathway in which both Lewisacid activation and iron‐enabled redox‐catalysis are crucial for selective azido‐group transfer.

catalytic system based on bianthrylbis(thiourea) for the asymmetric Henry reaction of fluoroketones and nitroalkanes that resulted from the screening of a library containing 31 chiral non-racemic organocatalysts. The corresponding adducts were isolated in up to 6 times shorter reaction time in comparison with the previously published organocatalysts. High levels of stereocontrol have been generally observed

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.
