Efficient methodology for the preparation of β-aminotetralin derivatives via electrophilic amination
摘要:
A mild and efficient method for the construction of beta-aryl amines from the corresponding alpha-aryl ketones is presented. The key steps of the synthesis involve an electrophilic amination by dibenzyl azodicarboxylate followed by a stereoselective LiHBEt3 reduction. The reaction sequence is applied to the synthesis of the tricyclic ergoline analogue 4.
