The 1H NMR spectra of cyclic carbonates and acetals of secondary-secondary glycolic systems can be used to estimate the ratio of erythro and threo isomers. The pinacols from four groups of achiral aldehydes with CpTiCl3-LiAlH4 as the reductive coupling agent were examined The threo isomers were found to be the major products.
