The ability of urea-linked oligomers of achiral diamines (achiral analogues of the well-established chiral oligourea foldamers) to adopt helical conformations was explored spectroscopically. Up to four achiral units were ligated either to a well-formed helical trimer or to a single chiral diamine, and the extent to which they adopted a screw-sense preference was determined by NMR and CD. In the best performing cases, a trimeric chiral oligourea and even a single cis-cyclohexanediamine monomer induced folding into a helical conformation.

HYDROXY PYRIDOPYRROLOPYRAZINE DIONE COMPOUNDS USEFUL AS HIV INTEGRASE INHIBITORS
-
Page/Page column 112, (2010/02/11)
Hydroxy-substituted pyridopyrrolopyrazine dione compounds are inhibitors of HIV integrase and inhibitors of HIV replication. In one embodiment, the dione compounds are of Formula (I): (I) wherein a, b, A, B, R1, R2, R3, R4, R5, R6, R7 and R8 are defined herein. The compounds are useful in the prevention and treatment of infection by HIV and in the prevention, delay in the onset, and treatment of AIDS. The compounds are employed against HIV infection and AIDS as compounds per se or in the form of pharmaceutically acceptable salts. The compounds and their salts can be employed as ingredients in pharmaceutical compositions, optionally in combination with other antivirals, immunomodulators, antibiotics or vaccines.
Selective synthesis of carbamate protected polyamines using alkyl phenyl carbonates
Pittelkow, Michael,Lewinsky, Rasmus,Christensen, Jorn Bolstad
, p. 2195 - 2202 (2007/10/03)
Utilising alkyl phenyl carbonates, an economical, practical and versatile method for selective Boc, Cbz and Alloc protection of polyamines has been developed. This method allows Boc, Cbz and Alloc protection of primary amines in the presence of secondary amines by reaction of the polyamines with the alkyl phenyl carbonates. Also, this method allows mono carbamate protection of simple symmetrical aliphatic α,ω-alkanediamines in high yields with respect to the diamine. Finally, the method allows selective carbamate protection of a primary amine located on a primary carbon in the presence of a primary amine located on a secondary or a tertiary carbon in excellent yields.
