  • 6-Substituted exomethylene 기를 갖는 penam계 화합물이 $\beta$-lactamase 억제제로서 강력한 활성을 보여주고 있어서, 6-exomethylene기 도입에 필요한 1-substituted thioalkyl-1,2,3-triazole-4-carboxaldehyde를 합성하였다. Haloalkanol에 NaN$_3$를 반응시켜서 합성한 azidoalkanol과 propargyl alcohol을 산화시킨 propargyl aldehyde를 반응시켜서 1-(2-hydroxyalkyl-1,2,3-triazole-4-carboxaldehyde을 얻었다. 이것을 trifluoromethanesulfonic anhydride와 triethylamine 존재 하에 mercapto 화합물과 반응시켜서 목적물을 합성하였다.

  • Stereochemical isomers with hydroxy groups were synthesized by reacting 2-(dimethoxy-methyl)cyclohexanone with propargylmagnesium bromide. The stereo chemical structures were identified by NMR spectral interpretation and the geometry optimization. To assist the NMR interpretation, geometry optimization based on semi-empirical AM1 and PM3 methods was applied. Throughout this study, the structures of the two isomers were all determined and $^{1}H$ and $^{13}C$ NMR spectra were fully assigned. It was proven that the less polar isomer is an axial alcohol and the more polar one is an equatorial alcohol.

  • Propargyl alcohol was coupled to 2,4-hexadiyne-1,6-diol (HDD) and crystallized in the process of ultraviolet irradiation-induced topochemical polymerization. The HDD polymer crystals were used as one component in the fabrication of organic photovoltaic cells, in combination with fullerene as the electron acceptor. The various structures of the produced photovoltaic cells included bilayer, trilayer, and bulk heterojunction structures. Their photovoltaic properties were analyzed in relation to crystal structure, electrochemical properties, and band structure of the HOD polydiacetylene polymers.

  • Reaction of $(E)-{\beta}-chloro-{\gamma}$-hydroxyvinylmercurials, prepared by mercuration of propargyl alcohol and 2-methyl-3-butyne-2-ol, with olefins in the presence of a catalytic amount of $Li_2PdCl_4$ and 2 equiv of cupric chloride in methanol at $50^{\circ}C$ gave the corresponding (E,E)-2,4-dienols in moderate yields. However, addition of 1 equiv of inorganic bases such as magnesium oxide to the reaction mixture brings a rapid and clean vinylation and gave high yields of the dienols at room temperature. In the case of hindered (E)-2-chloro-3-chloromercuri-2-buten-1,4-diol prepared from 2-butyne-1,4-diol, reaction with olefins gave the dienols only in low yields even in the presence of 2 equiv of magnesium oxide.

  • 배추좀나방의 성 페로몬을 새로운 방법으로 합성하여 EAG감응반응을 수행하였다. 프로파길알코올의 이중음이온을 알킬화하여 2-도데신-1-올을 얻고 이를 아세틸렌-지퍼반응에 의해 11-도데신-1-올로 전환시킨 다음, 다시 이중음이온 알킬화반응에 의해 11-헤사데신-1올을 얻었다. 이를 수소환원시켜 (Z)-11-헥사데센-1-올 (3)을 얻었고 이 알코올을 산화시켜 (Z)-11-헥사데센-1-알(1)을, 아세틸화시켜 (Z)-11-헥사데센-1-일 아세테이트(2)를 각각 얻었다. 이렇게 합성하여 얻어진 화합물 각각 또는 혼합물에 대해 배추좀나방의 ESG감응반응을 측정하였다.
