Abstract:
:The condensation of O-substituted hydroxylamines with conjugated 3-oxo-4-en steroids results in a mixture of syn-anti configurations. Syn-anti ratios are influenced by sterical hindrance between the oximino substituents (e.g. O-benzyl) and the steroidal skeleton. Stereostructures and isomeric ratios were proved by detailed 1H and 13C NMR studies and also by using 2D-COSY, 2D-HSC, DEPT, 2D-COLOC and DNOE measurements.
