The molecular structure of ryanodol-p-bromo benzyl ether

Abstract

The molecular structure of ryanodol-p-bromo benzyl ether was solved without any chemical assumptions, using three dimensional data obtained by the heavy atom technique. It was found to be identical with the structure proposed by Dr. K. Wiesner, except that the configuration was reversed at one carbon atom. The refinement of atomic parameters with a least-squares method is still in progress. The R factor is at present 0.12.
