We wish to report a simple one-step method for the partial resolution of racemic allenes based on the procedure of asymmetric hydroboration developed by H. C. Brown and coworkers('). Hydroboration of (-)-a-pinene in diglyme leads to (+)-sym-tetraisopinocampheyldiborane (lb) , I, which has been show

## Abstract It is shown unequivocally by chemical correlations (__cf. Schemes 1ββ3__) and __Raman__ optical activity spectra (__cf. Fig. 1__ and __2__) that the (__R__)βconfiguration has to be attributed to (+)β1βmethylindane ((+)β**1**). This is in contradiction to an earlier assignment of the (__
SINCE the absolute configuration of (+)-tartaric acid was established by Bijvoet et al., 1 the configuration of any other compound containing one or more asymmetric carbons may, in principle, be established by correlation with (+)-or (-)-tartaric acid. One of the remaining general problems of static
