Titanium with potassium graphite

Annelation of the A ring is accomplished by reaction of the appropriate 4-pentenal 525 with the kinetic enolate generated from 524 followed by ozonolysis of the olefin and cyclization of the resulting ketoaldehyde with potassium graphite-titanium trichloride. Oxidation of the alcohol under Swem conditions gives 527. [Pg.234]

Figure 059. Set-up for the preparation of lead-vi-chromate from potassium dichromate. The positive lead electrode will slowly be corroded in this operation. The Lead-VI-Chromate will form a flaky precipitate that will collect in the anode compartment. The negative lead electrode can be replaced with titanium, chromium, or graphite. Figure 059.
