Multicomponent synthesis of 4,4-dimethyl sterol analogues and their effect on eukaryotic cells
Most sterols, such as cholesterol and ergosterol, become functional only after the removal of the two methyl groups at C-4 from their biosynthetic precursors. Nevertheless, some findings suggest that 4,4-dimethyl sterols might be involved in specific physiological processes. In this paper we present...
