Homochiral cis epoxides derived from enzymatically asymmetrized tris(hydroxymethyl)methane equivalents (THYM*) are regioselectively opened by carbon based-nucleophiles (alkyl groups or cyanides) and halides in the presence of Lewis acids. Enantio- and diastereodivergent synthesis of branched triols is reported.
