    • Under the same conditions, by using an unencumbered amine such as piperidine, 1 and 2 wereobtained in 56 % and 31 % respectively ; however, by using 3 equiv. (instead of 1.5 equiv.) of 2-methyl-3-butyn-2-ol, the diol 2 was obtained in 82 % yield.

    • Under Pd-Cu conditions, when the reaction was performed at 22 % for 24h in triethylamine, piperidine or propylamine, by using 2-methyl-3-butyn-2-ol in excess (3 equiv.), the monosubstituted product 1 was obtained in 25% yield. The disubstituted product 2 was not formed.
