The intramolecular hydrogen bond in steroid 5‐hydroxy‐6‐ketones and 5‐hydroxy‐6‐ketoximes of the stigmastane series has been investigated by the method of IR spectroscopy. It is shown that 5β‐hydroxy groups in cis‐A/B‐steroids are linked by the intramolecular hydrogen bond with polar substituents at C3and C6. These hydrogen bonds are lacking in corresponding trans‐A/B‐steroids. According to the IR spectra, intramolecular associates of polymer type are formed in 5‐hydroxy‐6‐hydroxyminosteroids. |
