Abstract (en)
[origin: FR2685330A1] A method for preparing enantiomers of the product of formula (I) by hydrolyzing a diastereoisomeric acetal of general formula (II), wherein R1, R2, R3 and R4 are chiral diol residues. The dextrorotatory isomer of the product of formula (I) has anxiety-relieving, hypnotic, anticonvulsant, antiepileptic and muscle relaxant properties.
