Co(III) catalysed asymmetric ring-opening of epichlorohydrin by salicylaldehyde derivatives: reversal of enantioselectivity and rate acceleration on addition of AlCl3
Asymmetric catalysis salicylaldehyde Co(III) salen aryloxy alcohols epoxide ring-opening
2010/12/3
Using asymmetric Cobalt(III) salen catalysts, the ring-opening of epichlorohydrin by 2,3-dihydroxybenzal- dehyde and 2,4- dihydroxybenzaldehyde was found to occur at the phenolic groups most distant f...

Asymmetric synthesis of 8-O-4'-neolignan perseal B
Neolignans perseal B enantioselective synthesis
2010/10/18
Full details of an enantioselective total synthesis of 8-O-4'-neolignan perseal B are presented for the first time. The synthesis was achieved in 8 steps from vanillin and involved the asymmetric dihy...

Vapour Liquid Equilibrium in Asymmetric Mixtures of n-Alkanes with Ethane
Vapour liquid equilibrium Interaction parameters Asymmetric mixtures
2010/4/22
The paper presents a vapour liquid equilibria study in binary mixtures of n-alkanes with high dimensional asymmetry. Each mixture contains ethane and alkanes higher than eicosane. Calculations were do...
A synthetic approach is described to the asymmetric synthesis of ascochlorin (1), an antiviral antibiotic, based on the construction of a sesquiterpene unit via asymmetric Diels-Alder reaction of tigl...
