(2R)-1,1-diphenyl-pent-4-en-2-ol 25b (0.42 g, 1.75 mmol) was reacted with allyl bromide (0.63 g, 5.25 mmol) (Procedure B) to yield (2R)-1,1-Diphenyl-2-Allyloxy-Pent-4-en 26b, 0.43 g (87%, [α]D=(−)20, c=1, MeOH). The 1HNMR and 13CNMR were identical with (2R)-1,1-diphenyl-2-alluloxy-pent-4-en shown above.
