Pa. Brady et al., LIVING MACROLACTONISATION - THERMODYNAMICALLY-CONTROLLED CYCLIZATION AND INTERCONVERSION OF OLIGOCHOLATES, Chemical communications, (3), 1996, pp. 319-320
Cyclocholates are efficiently and rapidly synthesised from suitable mo
nomers by transesterification under thermodynamic, equilibrating condi
tions using a potassium methoxide-crown ether complex.
