To a solution of Methyl (2E)-3-phenylprop-2-en-1-yl carbonate (1.5 g) in THF (25 ml), was added N,N-bis[(1S)-1-phenylethyl]dinaphtho[1,2-f:2′,1′-d][1,3,2]dioxaphosphepin-4-amine (420 mg), and chloro(1,5-cyclooctadiene)iridium(I) dimer (105 mg) at RT under N2. The mixture was heated at reflux overnight. Evaporated material then redissoled in a 50:50 mixture of EtOH:THF. To this solution was added macro porous p-toluenesulfonic acid resin (10 g) and the mixture was gently agitated for 3 h. At this time the resin was washed completely with THF, THF:EtOH and EtOH. To a suspension of the resin in MeOH (75 ml) was added 7 N NH3.MeOH (75 ml). This mixture was gently agitated for 2 hours and filered, washing with MeOH, THF, THF:MeOH, and DCM. Evaporating this filtrate left a yellow oil (1.2 g). This oil was then distilled on a kuglerohr vacumme distilation aparatus. This left the title compound as a clear oil.
