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.
