A handy new ligand: The CpRu complex (Cp=cyclopentadienyl) of a new type of chiral bisamidine ligand with a naphtho[1,2-b:7,8-b]dipyrroloimidazole (Naph-diPIM) skeleton with a Bronsted acid efficiently catalyzes dehydrative intermolecular C-allylation with high enantio- and regioselectivity. The catalytic system also gives nearly enantiomerically pure cycloalkanes and N- and O-heterocycles with a substrate/catalyst ratios of up to 10 000.
Asymmetrie dehydrative cyclization of ω-hydroxy allyl alcohols catalyzed by ruthenium complexes

supporting information; experimental part, p. 8948 - 8951 (2010/02/27)
New axially chiral ligands and their allyl esters have been designed and synthesized. The combination of these ligands with [CpRu(CH3CN)3]PF6 has realized highly efficient intramolecular dehydrative cylization of w-hydroxy allyl alcohols, to give a-alkeny
