Photochemische Studien, 54. Photodimerisierung von Testosteronpropionat in kristallinem Zustand und Kristallstruktur von Testosteronpropionat

Abstract
Photochemical Studies, 54. ‐ Photodimerization of Testosterone Propionate in Solid State and Crystal Structure of Testosterone PropionateOn UV irradiation, testosterone propionate (1) dimerizes in solid state to give 6ζ‐(3‐oxo‐17β‐propionyloxy‐5ζ‐androstan‐4ζ‐yl)‐17β‐propionyloxyandrost‐4‐en‐3‐one (4). As shown by an X‐ray analysis of 1, the structure of the topophotodimerization product 4 is determined by the molecular packing of 1 in the crystal.
