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].
