Versuchsvorschrift

Procedure 3 is illustrated with the preparation of (-)-(RR)-8a' and (+)-(RR)-8b', with (-)-(R)-6f' as a byproduct. In dry pyridine at 0°, N,N-bis-(2-hydroxyethyl)-p-toluenesulfonamide (m.p. 96°-99°) was tosylated with tosyl chloride by the standard method to give N,O,O'-tritosyldiethanolamine, m.p. 85°-87°. [Can. J. Chem. 45, 1555 (1967) gives 78°-79°].
