Ionic mechanism for the cyclization of squalene to steroids according to Ruzicka (20). presented a comprehensive reaction scheme which connects squalene with the steroids as well as with the various pentacyclic triterpenes, and serves as a highly stimulating working hypoth- esis for future biochemical work (20). According to Ruzicka the cyclization of squalene is initiated by a cationic attack at the carbon atom which corresponds to C3 of the steroid skeleton, one of the two positions which are most susceptible to attack by electrophilic reagents. Thereafter, the tetracyclic ring system is 480
