Reaction Steps
(2S)-2-benzhydryl-oxirane (0.61 g, 2.91 mmol) was reacted with vinylmagnesium bromide (7.26 ml of 1.0M solution in THF, 7.26 mmol) in the presence of CuI (0.055 g, 0.29 mmol) (Procedure A) to yield (2R)-1,1-diphenyl-pent-4-ene-2-ol 0.48 g (70%, [α]D=(+)26, c=1, MeOH). The 1HNMR and 13CNMR were identical with (2S)-1,1-diphenyl-pent-4-ene-2-ol.
