실험 절차
Cleavage of the THP ether from crude 2-(pentadec-2-ynyloxy)tetrahydro-2H-pyran (30 g) using PTSA as described above gave pentadec-2-yn-1-ol (18.6 g, 85%) as a colorless oil. TLC: 30% EtOAc/hexanes, Rf≈0.40; 1H NMR (CDCl3, 300 MHz) δ 4.25 (s, 2H), 2.17-2.23 (m, 2H), 1.70 (br s, 1H), 1.40-1.53 (m, 2H), 1.20-1.48 (m, 18H), 0.87 (t, 3H, J=7.3 Hz).
