(P1) and (F1): The spectra of 2d and BF3·OEt2 in toluene, respectively. (P2) and (F2): The spectra of the product obtained by adding BF3·OEt2 in 2d in toluene, respectively. (P3) and (F3): The spectra of the product obtained by adding 1a in the product of (P2)/(F2), respectively. (P4) and (F4): The spectra of the product obtained by adding CH3OH in the product of (P3)/(F3), respectively.
