Preparative high performance liquid chomatography on straight silica gel of fermentatio liquor of Streptomyces erythreus
(University of Nairobi, 1984)
Isolation of erythromycins and related substances from fermentation residues of strepto.'i1yces erythreus by high-performance liquid chromatography on silica gel
(1985)
Preparative high-performance liquid chromatography on silica gel allows the isolation of erythromycins and related substances from mother-liquor concentrates. Three mobile phases were used consecutively: A, ethyl ...
Translactonization in Erythromycins
(1987)
When erythromycin A is heated in diethylamine-acetic acid. an erythromycin hemiketal is obtained, which can be further transformed into a new enol ether and spiroketal. The new euol ether is also obtained in equilibrium ...
