Cationic Copolymerization of Cholesterol Vinyl Ether with N-Allenylpyrrolidone: A Route to Pharmacologically Promising Oligomers

Аннотация

Cationic copolymerization of cholesterol vinyl ether with N-allenylpyrrolidone yielded co-oligomers with molecular mass of 1200–2100. The polymerization of N-allenylpyrrolidone involves both 1,2- and 2,3-positions of the allenyl substituent to give four types of units as a result of prototropic isomerization of the initially formed structures. In the developed method, the composition of co-oligomers can be controlled and, hence, their hydrophilic/hydrophobic balance, solubility, and membranotropic properties can also be contolled to change the potential biological activity of the products.
