Aromatic electrophilic substitution of aromatic/electron rich heteroaromatic compounds with AlBr3 activated aldehydes/ketone to afford pyridyl aryl/heteroaryl or diaryl carbinols is described. The strong electron donating group dictates the regiochemical outcome of the product.
Enantiopure (9-Anthryl)(2-piperidyl)- and (9-Anthryl)(2-pyridyl)methanols – Their Use as Chiral Modifiers for Heterogeneous Hydrogenation of Keto Esters over Pt/Al2O3
toward the synthesis of the erythro isomer of (9-anthryl)(2-piperidyl)methanol is presented as well as resolution and assignment of the structure (through NMR). The use of both the erythro and threo enantiopure isomers of this newaminoalcohol, and its precursor [(9-anthryl)(2-pyridyl)methanol], as chiral modifiers for the Pt/Al2O3 hydrogenation of ethyl lactate showed that the erythro isomer is not
