New quina alkaloid unsaturated urethane derivatives

摘要

Quina alkaloid unsaturated urethane derivatives of formula (I) are new. R1 = H or OMe; R2 = ethyl or vinyl; R3 = 3-16C divalent organic group, optionally containing an ester residue; R4 = H or Me. Also new are polymers (II), obtained by radical polymerisation of (a) 10-100 wt.% (I), (b) 0-80 wt.% other vinylic unsaturated compounds and (c) 0-20 wt.% vinylic polyunsaturated compounds, in presence of (d) 0-10000 wt. % silica gel.
