    • 2 at room temperature for 3.5 h. After filtration, the crude product was chromatographed on silica gel (2 g; eluent: hexane-ethyl acetate (6:1)) to give 5a (16.7 mg, 79% yield) as an inseparable diastereomeric mixture.

    • The α-methin proton of syn-5 resonated in lower field compared to that of anti-5 (see, Ref. 3). The diastereomer ratio of 5 was determined by the integration of α-methin protons.
