“…[31] 7. 8 [35] Die modifizierte Variante [34] der Sarett-MerckSynthese ist in Schema 17 skizziert. Die Sarett-Merck-Synthese wurde unter anderem deshalb nie kommerzialisiert, weil die Enantiomerentrennung schwierig war und erst auf der (späten) Stufe eines fortgeschrittenen tricyclischen Intermediats erreicht werden konnte.…”

“…The sequence of reactions for the construction of ring D was based on the method developed by Sarett and co-workers for the synthesis of cortisone [113,114] (See Chapter 9, Section 9.4). The unsaturated ketone 133, was alkylated via the hydroxymethylene derivative 134 to give the ketone 135.…”

“…The elegance in the total synthesis of cortisone (70, R = H) by Sarett and co-workers [27][28][29][30][31][32][33][34][35][36][37][38][39] lies in the fact that a high degree of stereospecificity was maintained in each step. Besides this, no relay compound was involved in their reaction scheme.…”

“…In the first of them [33,35], reduction of the free acid 54 or its methyl ester with lithium aluminum hydride produced the diol 55 in good yield. Selective tosylation and subsequent oxidation with chromium trioxide-pyridine complex afforded the ketotosylate 57.…”
