Narcotic drug methohexital: synthesis by enantioselective catalysis.

The narcotic drug methohexital 1 contains two asymmetric carbon atoms and, thus, consists of four isomers, two diastereomeric pairs of enantiomers. The commercial drug is the so-called alpha-racemate, one pair of diastereomers only. A method was developed to prepare differently enriched mixtures of methohexital isomers without resorting to lengthy and… CONTINUE READING
