Table 2. Substrate Scope^a.

^aReactions were conducted on 0.25 mmol scale.

^bIsolated yield and ee of purified product before recrystallization. The structure and absolute configuration of 3k were established by X-ray crystallography, and the stereochemistry of all other products was assigned by analogy.

^cNumbers in parentheses correspond to the isolated yield and ee after recrystallization. For details on the recrystallization procedure, see the Supporting Information.

^dReaction was conducted on 1 mmol scale.
