- W1990692910 abstract "The crystal structure of the alkaloid eserine, a constituent of the Calabar bean, Physostigma venenosum Balf., has been determined from diffractometer data. Crystals are orthorhombic, space group P212121, a= 1458(1), b= 1435(1), c= 727·1(6) pm, Z= 4. The structure was solved by multi-solution direct methods and refined by block-diagonal least squares to R 0·06 (1521 significant reflections) and R 0·10 (all 2531 observations). These results confirm those obtained by use of the nuclear Overhauser effect, and show that the solid-state conformation, at least of the three fused rings, persists in solution. The two pyrrolidine rings are cis-fused. That fused to the benzene ring is almost flat, and the other is in the C2 half-chair conformation with a two-fold symmetry axis passing through C(8) and the mid-point of the C(6)–C(10) bond." @default.
