chiral cyclobutanone 3 was effectively achieved with [1,4-bis(diphenylphosphino)butane](1,5-cyclooctadiene)rhodium (1) tetrafluoroborate as catalyst to give the olefins 7 and 8 which were converted into (−)-α-bisabolol 1a and (+)-4-epi-α-bisabolol 15via9 and 10, 11 and 12, and 13 and 14.
以[1,4-双(二苯基膦基)丁烷](1,5-环辛二烯)铑(1)四氟硼酸酯为催化剂,有效地实现了由手性环丁酮3合成的环己二烯6的区域控制加氢,得到烯烃7和8其转化为( - ) - α红没药醇1A和(+) - 4-表-α红没药醇15通过9和10,11和12,以及13和14。
