반응 단계
Methyl 10-undecynoate was prepared via the reaction of 10-undecynoic acid (Farchan) with diazomethane. The ester (1.6 g, 8 mmole) was hydroborated with catecholborane. The yield of the boronic acid was 1.7 g (87%); mp 48.5-50; mass spectrum, 316.9 (calcd. m/e316.1); NMR (CDCl3) 1.3 δ(broad s, 12H, alkane), 2.35 (broad envelope, 4H, --CH2CH=,--CH2CO2), 3.6 (s, 3H, --OCH3), 5.38 (d, 1H, --C=CHB, J=17 Hz), 6.4 (m, 1H, --CH=CHB).
