At the time Nozo was researching how to extract new chemical products from camphor oil produced from Mt Ali's forests. He had experimental results showing that its organic heteroaromatic compounds had six-sided as well as seven-sided varieties. From this he built a basis for trophone chemical research and earned a Nobel nomination.
當時野副教授正專注於研究從阿里山檜木精油提煉新化合物，他由實驗結果推論有機化合物的芳香性環狀化合物除了有六角形的，應該還有七角形的，從此建立了「卓酮類」化學研究的基礎，還一度入圍諾貝爾獎候選人。
