摘要:
This invention is directed to a method for isolating and/or purifying one or more taxanes from materials comprising taxanes. In one embodiment, the method comprises the steps of: (a) treating a taxane containing material with an amino containing material attached to a solid matrix, such as a polyethyleneimine-bonded silica chromatographic resin; (b) eluting the desired taxane compound from the resin; and (c) recovering the eluted taxane compound.
摘要:
The invention provides methods and compositions for reductively deoxygenating an amide group at a C-3′ position of a taxane molecule followed by subsequent intra-molecular acyl migration of an acyl group to the C-3′ position.
