  为了阐明氘同位素效应（DIE）在信息素活性中的作用，并探讨4,8-二甲基癸醛（4,8-DMD；1）的生物合成途径，合成了4,8-DMD的氘代类似物（2、3、4和5），并使用双孔坑式嗅觉仪测试了它们的信息素活性。尽管在它们的信息素活性中未观察到明显的DIE，4,8-DMD-1-d1（2）的吸引力低于其他类似物，这表明1的羰基与其受体之间的键长在T. castaneum对信息素的识别中是关键因素。版权 © 2004 John Wiley & Sons, Ltd.

• Biosynthesis of 2-Methylbutyl, 2-Methyl-2-butenyl, and 2-Methylbutanoate Esters in Red Delicious and Granny Smith Apples Using Deuterium-Labeled Substrates

  2-Methylbutanoate esters, especially ethyl 2-methylbutanoate, are key contributors to fruit aroma. The biosynthetic origins and interconversions of 2-methylbutyl and 2-methylbutanoate esters in Red Delicious and Granny Smith apples were determined by feeding deuterium-labeled substrates with GC-MS identification of the deuterated aroma volatiles produced. Deuterium-labeled isoleucine was fed to apple peel, and 2-methylbutanoic-d(3) acid, 2-methylbutanol-d(3), and ethyl 2-methylbutanoate-d(3) were fed as vapor to whole apples. An array of labeled 2-methylbutyl and 2-methylbutanoate esters was produced from each substrate with significant differences in products and product distributions between the two apple cultivars. Novel 2-methyl-(2E)-butenyl esters were identified as biosynthetic products in the aroma of Red Delicious but not Granny Smith apples.

  To elucidate the deuterium isotope effect (DIE) in pheromonal activity and to investigate the biosynthetic pathway of 4,8-dimethyldecanal (4,8-DMD; 1), the aggregation pheromone of the red flour beetle (Tribolium castaneum), deuterated analogues of 4,8-DMDs (2, 3, 4, and 5), were synthesized and their pheromonal activities were tested using a two-hole pitfall olfactometer. Although no apparent DIE was observed in their pheromonal activities, 4,8-DMD-1-d1 (2) was less attractive than other analogues, which suggested that the bond distance between the formyl group of 1 and its receptor was critical in pheromone recognition by T. castaneum.
