The isolated forms presented strongly solvent and concentration dependent optical rotations. The racemization barriers of the tetramethyl 69 and tetraethyl 70 analogues were determined in 0.1 N NaOH solution by polar-imetry. The resulting barriers were equal to 115.8 and 133.3 kj mol , respectively. The origin of the barrier difference is enthalpy driven and results from the larger steiic size of the ethyl group compare to the methyl group. [Pg.44]
