Remote stereocontrol as a synthetic strategy: diastereoselective annulations on an arene tricarbonylchromium template
†
Abstract
Stereoselective annulations on Cr(CO)3 complexed tetralone and benzosuberone§ derivatives have been achieved. Diastereomeric products are shown to be related by an epimerisable chiral centre. An unusually facile de-ethoxycarbonylation has been observed.
