Abstract
An examination of the N.M.R. spectra of ceanothic acid and derivatives has led to its formulation as 2α-carboxy-3β-hydroxy-A(1)-norlup-20(29)- en-28-oic acids (1; R = H) in which the carboxy and hydroxy groups attached to ring A have the inverse of the trans configuration originally assigned to them by de Mayo and Starratt.1
