Abstract	Crown 고리 근방에 질소, 황원자를 포함하는 새로운 2종의 Crown ether를 합성하였다. 4'-Benzothiazolylbenzo-12-crown-4 (1) 4'-benzothiazolylbenzo-15-crown-5 (2)는 각각 4'-formylbenzo-12-crown-4 (3) 및 4'-formylbenzo-15-crown-5 (4)와 2-aminothiophenol과의 반응에 의해 합성하였다. (3)과 (4)는 3,4-dihydroxybenzaldehyde와 tri- 및 tetraethyleneglycolditosylate와의 반응에 의해 합성하였다. Triethyleneglycolditosylate와 tetraethyleneglycolditosylate와의 반응에 의해 합성하였다. Triethyleneglycol, tetraethyleneglycol과 p-toluenesulfonyl chloride의 반응에 의해 합성하였다. Two new crown ethers containing nitrogen and sulfur atoms adjacent to the crown rings were prepared. 4'-Benzothiazolylbenzo-12-crown-4 (1) or 4'-benzothiazolylbenzo-15-crown-5 (2) were synthesized by reaction of 2-aminothiophenol with 4'-formylbenzo-12-crown-4 (3) or 4'-formylbenzo-15-crown-5 (4) respectively. (3) and (4) were obtained by reaction of 3, 4-dihydroxybenzaldehyde with tri- or tetraethyleneglycol ditosylate. Triethyleneglycol ditosylate or tetraethyleneglycol ditosylate were synthesized by reaction of p-toluenesulfonylchloride with triethyleneglycol or tetraethyleneglycol in the presence of sodium hydroxide.
