In a rational approach to identify an ultrapotent compound for the treatment of therapy-resistant dermatoses, Weirich's modification of McKenzie's skin vasoconstriction assay (HVK test) has been used as the essential selection criteria. In a primary

The 2,4-bis-functionalized phenol 1 is dehydrogenated regioselectivity with potassium ferricyanide, affording the corresponding p-quinonemethide 2. Hydrolysis of 2 affords a mixture of dithioacetal 5a and benzaldehyde 6; 1,6-addition of thiols to 2 g
