Treatment of the prochiral triflate 2a with Pd2(dba)3·CHCl3, (S)- (R)-BPPFOAc and K2CO3, in THF at 40°C, gave the cyclopentane derivative 10 in 58% yield and in 28% ee after oxidative work-up and benzoylation. Moreover, reaction of the prochiral triflate 2c with Pd2(dba)3·CHCl3, (S)-(R)-PPFA and K2CO3, in THF at 40°C, afforded the cyclopentane derivative 3b, with a quaternary carbon center, in 42% yield and in 31% ee after oxidative work-up.
