Abstract
The total synthesis of racemic aldosterone (I) was achieved recently by J. Schmidlin, G. Anner, J.‐R. Billeter and A. Wettstein A. Wettstein at the XIVth International Congres of Pure and Applied Chemistry, July 1955, Zürich. Experientia 11, 365 (1955). . Our own efforts in the field of the total synthesis of adrenal cortical hormones and derivatives will be described in the present and forthcoming papers See Experientia 11, 365 (1955), footnote 2.
