Abstract
Abstract A practical and selective method for the synthesis of the β-arylamines 5 and the cis- or trans-amino alcohols 8 or 11 is reported. The reaction sequence starts from α-tetralones 1 which readily react with dibenzyl azodicarboxylate to afford the protected α-hydrazino ketones 2. Then, depending on the reduction conditions, the trans-hydrazino alcohols 10 or the cis isomers 7 are formed predominantly. The stereoselectivities which range between ...
