Die Stellung des Arztes in der römischen Gesellschaft
It is twenty years since Sir George Clark published his official history of the Royal College of Physicians. His book was liked by the establishment, but it was given a restless reception by younger historians. Since then a great deal of effort has gone into this subject.

متن کامل7α-Methoxycarbonyl-6,7,8,14-tetrahydro-6,14-endo-ethenothebaine
In the mol-ecule of the title compound, C(23)H(27)NO(5), the furan ring adopts an envelope conformation. Intra-molecular C-H⋯O inter-actions result in the formation of S(5) and S(6) motifs. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules through C(6) and C(8) chains along the [100] and [010] directions, generating a two-dimensional network.
متن کاملN-Cyano-7α-methoxycarbonyl-6,14-endo-ethenotetrahydronorthebaine
IN THE TITLE COMPOUND (SYSTEMATIC NAME methyl 17-cyano-3,6-dimeth-oxy-4,5α-ep-oxy-6,14-endo-ethenomorphinan-7-carboxyl-ate), C(23)H(24)N(2)O(5), the dihydro-furan ring adopts a twist conformation, while the piperidine ring is in a chair conformation. The benzene-fused cyclo-hexene ring adopts an envelope conformation. An intra-molecular C-H⋯O hydrogen bond is observed. Inter-molecular C-H⋯N and...
