Abstract
On the basis of the specific rotation and n.m.r. data of several derivatives of lythranidine, the trans-relationship between C-5–H and C-9–H and between C-3–H and C-11–H has been deduced. An X-ray analysis of bromolythranine hydrobromide by Sim and McClure, jun. has clarified its structure, (XIII), and absolute configuration. Consequently, it has been possible to assign the structures and absolute configurations to lythranine (XIV), lythranidine (XV), and lythramine (XVI).Keywords
