One-step construction of aza-polycyclic skeletons was realized through double cyclization of the oxocarbenium and carbocation intermediates generated from α-amino acetals, which were designed and synthesized by employing our α-amination protocol of aldehydes. A simple process, a broad substrate range, commercialized materials, and extensive applications demonstrated the generality and effectiveness of this method.

The innate immune restriction factor SAMHD1 can inhibit diverse viruses in myeloid cells. Mechanistically, SAMHD1 inhibits lentiviral replication including HIV-1 by depleting the nucleotide pool to interfere with their reverse transcription. Equine infectious anemia virus (EIAV) is an ancient lentivirus that preferentially attacks macrophages.
