ABSTRACT: A convenient two-step protocol prepa-ration of cineol (1-isopropyl-4-methyl-7-oxabicyclo-[2,2,1]heptane) from -terpineol (p-menth-1-en-8-ol)is reported. The phenylselenoetherification of -ter-pineol with PhSeX (X = Cl, Br, I) as a key step isdescribed. -Terpineol reacts with PhSeX to form thecorresponding phenylselenoether in short reactiontime and in quantitative yield. A subsequent reduc-tion
摘要:从-萜品醇 (p-menth-1-en-8-ol) 制备桉树脑 (1-异丙基-4-甲基-7-氧杂双环-[2,2,1]庚烷) 的便捷两步方案)被报道。描述了-ter-pineol 与 PhSeX (X = Cl, Br, I) 的苯基硒醚化作为关键步骤。- 萜品醇与 PhSeX 反应,在较短的反应时间内以定量收率形成相应的苯基硒醚。随后用 Bu 3 SnH 还原为桉树脑,收率高 (98%) C 2004 Wiley Periodicals, Inc.
