Aa. Bredikhin et al., Cyclic (4S)-chloromethyl sulfite and sulfate derivatives of (S)-glycidol as valuable synthetic equivalents of scalemic epichlorohydrin, MENDELEEV C, (6), 1999, pp. 236-237
The interaction of (S)-glycidol with SOCl2 or SO2Cl2 in stoichiometric amou
nts leads to the formation of cyclic (4S)-chloromethyl sulfite or sulfate d
erivatives with the same enantiomeric purity; based on this reaction, a new
procedure for the synthesis of (S)-propranolol was developed.
