note

A referee suggested the interaction between the oxygen atom of substrates and Lewis acids may be responsible for the differences in enantioselectivity observed for 8a (Table 4, entry4, ee: 37%) and dimethyl derivative 36 (Table 5, entry 3, ee: 93%). This is a plausible explanation for the differences, but the results in the carbon series were not available and therefore we cannot discuss such an interaction at the present time.
