It is shown unequivocally by chemical correlations (cf. Schemes 1--3) and Raman optical activity spectra (cf. Fig. 1 and 2) that the (R)-configuration has to be attributed to (+)-1-methylindane ((+)-1). This is in contradiction to an earlier assignment of the (R)-configuration to (−)-1[2] which was based on the (R)-configuration of (+)-indane-1-carboxylic acid (3) [11].
化学相关性(参见方案1--3)和拉曼光学活性谱(参见图1和2)明确显示,(R)-构型必须归因于(+)-1-甲基
茚满( (+)- 1)。这是矛盾的(早期分配- [R )-构型,以( - ) - 1 [2],它是基于([R )(+)-构型的-
茚满-1-
羧酸(3)[11 ]。
