It is rather important to carry out these experiments in diethyl ether to achieve good yield and regioselectivity.

note
-
The low diastereoselectivity of the conversion from 10 to 6 with TMEDA/s-BuLi indicated a close resemblance between the phenyl group and the isopropenyl group for the diamine-assisted enantioselective lithiation chemistry on α-stereogenic carbamate substrates.

note
-
The er on C2 from the deprotonation with TMEDA/s-BuLi was not the same for products 6 and 7. This is because (S)-phenyloxiranes of different enantiomeric purities from different batches were applied as the starting material.
