Subjects
*TRIAZOLES, *CARBON-carbon bonds, *PHASE-transfer catalysis, *DENDRIMERS synthesis, *ELECTROCHEMISTRY, *ROTAXANES synthesis
Abstract

In addition to the first generation dendrimer (III) and the second generation dendrimer (VIII) analogues dendrimers were synthesized employing 1,2-bis(azidomethyl)benzene or 1,2,4,5-tetrakis(azidomethyl)benzene instead of (I). [ABSTRACT FROM AUTHOR]

11. ChemInform Abstract: Enantioselective Ullmann Ether Couplings: Syntheses of (-)-Myricatomentogenin (VIII), (-)-Jugcathanin (X), (+)-Galeon (III), and (+)-Pterocarine (IV).

Author

Salih, M. Quamar and Beaudry, Christopher M.

Subjects
*ENANTIOSELECTIVE catalysis, *COUPLING reactions (Chemistry), *ETHERS, *ETHERIFICATION, *PHASE-transfer catalysis, *CHIRALITY, *RING formation (Chemistry)
Abstract

The optimized Ullmann ether couplings by using N-methyl-L-proline as chiral catalyst render possible the enantioselective cyclization of compounds (I) and (V) to give the axial chiral cyclophane products which can be selectively deprotected to give the title species without loss of enantioselectivity.
