titleOfInvention |
Aryl ketals of polycyclic oxo compounds and processes |
abstract |
The intermediates and processes of this disclosure provide a new stereo-specific total synthesis of steroidal materials having known valuable pharmacological properties. A fundamental feature of this disclosure is the utilization of aryl ketals, preferably phenylenedioxy ketals derived from catechol as protective groups for oxo moieties in the polycyclic intermediates used in the aforesaid total synthesis. |
