NaH (7.5g, 60% kuparadzirwa kwemafuta, 326mmol) yakawedzerwa batch nebatch kune dodecyl -3-alkyne -1-doro (10.0g,54.95mmol; GF Smith) mune yakamutswa 0 ℃ mhinduro ye ethylenediamine (40mL). Mushure me1h, tembiricha yakasimudzwa kusvika 70 ℃. Mushure meimwe 8h, tonhorera musanganiswa wekuita kusvika 0 ° C, nyatso gumisa nemvura inotonhora yechando (100mL), uye bvisa ne ether (3 × 60mL). Iyo yakasanganiswa ether extract yakashambidzwa nemvura (100mL). Mvura yekugeza yakadzoserwa shure-yakabudiswa ne ether (3 × 60mL). Izvo zvakasanganiswa organic zvinyorwa zvakanyungudutswa pasi pevacuum, uye zvakasara zvakaiswa pasi pekoromu chromatography vachishandisa 10% EtOAc/hexane kuwana 11-dodecyne -1-doro (7.4g,74%) yakasvibiswa ne3-5% yemamwe maisomers edunhu. regioisomer).
