Induced Asymmetry of Unsaturated Radicals in Optically Active Compounds

Nature volume 113, page 785 (31 May 1924) | Download Citation



IN their interesting letter in NATURE of April 19, Prof. T. M. Lowry and Dr. E. E. Walker made no reference to the work of Erlenmeyer upon induced optical activity in cinnamic acid (various papers in the Biochemische Zeitschrift during the last fifteen years). Erlenmeyer's results, if substantiated, would be of fundamental importance, and in view of the desirability of further investigation, I have been engaged for some time, in collaboration with Dr. S. I. Levy, in a repetition of those experiments in which Erlenmeyer claims to have obtained optically active cinnamic acid by the fusion of the acid itself, its anhydride and chloride, with d-tartaric acid. We hope to communicate the results of our investigation to the Chemical Society during the present year.
