Abstract:
Heating of dehydroepiandrosterone under nitrogen with a concentrated solution of SbCl3 in C6H5COCl (3 h at 90 degrees C) leads to a dark violet-coloured crystalline product of the composition C38H46Cl7O2Sb2 with antomony in a trivalent state. Treatment with hydrochloric acid yields an antomony-free brown-coloured product of the composition C38H40O2 with a molecular weight of 530 +/- 10%. Upon catalytic hydrogenation, it binds 6 moles of H2, yielding a yellow crystalline material which reacts already at room temperature with dilute SbCl3 to a bluish-violet solution. The structure of the substances in question is discussed.

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
