摘要
归纳阐述了存在手性碳原子的环己烷判断R/S的方法为"环己烷的构象转为费歇尔时,环碳在横向,编号61234561a,e,上下交替换,奇碳a上e下,偶碳e上a下.对映体椅型结构互转变,编号顺变逆,ae,键基团位不变,-对映构型只是R变S,S变R",并应用举例.
This paper summarized the easy way of the judgement enantiomer(R/S) of the chiral carbon atoms in cyclohexane,"The way of the conformation of cyclohexane to Fischer is,carbon atoms in Ring is horizontal,No.61234561,a and e bond replacement pay from above to below,on Odd carbon a chemical bond in the above e chemical bond below,vice versa.Enantiomers chair structure changes in each other,code-change inverse,a and e chemical botton remain unchanged,only R for changes in S,vice versa",and its applications.
