In order to investigate the structure-odor relationship of odoriferous compounds andsearch for new aroma chemicals, seven acetals of 4-trimethylsilyl-3-cyclohexenone and their carboncounterparts were synthesized by Birch reduction of 4-substituted anisoles and then acetalization.Seven acetals of 4-trimethylsilylcyclohexanone and their carbon counterparts were synthesized similarly.Structures of all new compounds were determined by MS, IR and ~1H NMR, and their characteristicodors were evaluated as well. The characteristic odors of the acetals formed by 4-substituted-3-cyclohexenone and 1, 2-diols arefruity and woody. The acetals formed from 1, 3-diols are woody, and formed with 1, 4-diols arevery faint in odor. Odors of acetals of 4-substituted cyclohexanone are all very weak. As a whole,odors of organosilicon compounds are weaker, but somewhat more delicate than their carbon counter-parts.

小威和纳达尔夺冠，这是一届圆满的法网，因为最大的热门也笑到了最后。圆满的同时这也有点无聊，当人人都能预见到最后的结果，这个比赛还打个什么劲儿？这都不太像比赛，更像是有剧本而且经过彩排的巡演——从马德里到罗马再到巴黎，纳达尔和小威联手统治了今年的欧洲红土赛季。 5月26日威廉姆斯姐姐输给拉德万斯卡妹妹了，也就是说大威输给u拉了。去年当大威输给A拉时，她还有点诧异，现在已经可以平静接受任何结果了。倒
