The enantioselectivity was determined by chiral GC (chiraldex B-DM). The absolute configuration of 2-methyl-2-tolylcyclobutanone was determined by comparing the measured optical rotation with the reported one (ref 4a). The absolute configuration of 2-(p-tert-butylphenyl)cyclobutanone was tentatively assigned based on mechanistic considerations.
