stereochemical information from the chiral center at the propargylic ether in the alkyne to the planar center of chirality in the in situ generated arene chromium tricarbonyl complexed intermediate and finally, after base-induced elimination to generate an o-quinone methide chromium tricarbonyl complexed intermediate, a transfer of chiralityfrom the planar center of chirality in the o-quinone methide
