(S)-(-)- and (R)-(+)-Frontalin were synthesized, respectively, in high enantiomer excess from β-methallyl alcohol (2) by three-step procedure; (i) asymmetric epoxidation of 2, (ii) the epoxide opening with homoallylmagnesium bromide, and (iii) Pd(II)-catalyzed intramolecular acetalization.

O-Dephenylandarine and O-dephenylostarine, two SARM metabolites relevant for doping control analysis, were synthesized in their endogenous (S)-forms as well as in terms of their racemates. The enantiopure (S)-metabolites were obtained after six steps in 20% and 23% overall yield, the slightly modified racemic route provided the compounds in 28% and 31% total yield, respectively.
