概要 The polyaddn. of L-lysine hydrochloride and bifunctional bisphenol A-derived five-membered cyclic carbonate (CC) was carried out in dimethylacetamide in the presence of 1 equiv of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) or 2 equiv of sodium hydride for 24 h to afford optically active polyurethane bearing hydroxy and carboxyl group. The polyaddn. of L-lysinol and CC was also carried out in N-methylpyrrolidone to afford higher-mol.-wt. optically active polyurethane bearing hydroxy group in quant. yield. These polyurethanes reacted with cupric acetate, sodium tetrahydroborate, and titanium tetraisopropoxide to afford the corresponding crosslinked gels immediately.
