T. Nabeshima et al., FACILE SYNTHESIS OF THIOLARIAT ETHERS OR CROWN-ETHERS CONTAINING A MERCAPTO GROUP AS A SIDE ARM, Bulletin of the Chemical Society of Japan, 68(1), 1995, pp. 227-229
Cyclization reaction of S-substituted thioglycerol and oligoethylene g
lycol ditosylate gave thiolariat ethers in moderate yields. Mercaptome
thyl crown ethers were obtained easily from benzylthiomethyl crown eth
ers by Na in liq. NH3-BuOH.
