Starting from tetrahydrothiopyran-4-one (4d) a rational NMR spectra, redox behavior, and crystal structure (H 4 -3a and 3a). The very low solubility of 3a and 3b prevented eight-step synthesis of 3a has been developed with 25 % overall yield. This route passes H 4 -3a and H 2 -3a which are further r
