HCID 674233292-(pentadec-2-ynyloxy)tetrahydro-2H-pyran수율 80%

실험 절차

Alkylation of 2-(prop-2-ynyloxy)tetrahydro-2H-pyran (15.5 g, 110.71 mmol) with 1-bromododecane (34.0 g, 132.04 mmol) as described above gave 2-(pentadec-2-ynyloxy)tetrahydro-2H-pyran (27.2 g, 80%) which was used without further purification. TLC: 10% EtOAc/hexanes, Rf≈0.5.
