Abstract
thietane-2,4-diylidenebis(cyanomethylphosphonates) and -phenylphosphin ates (1/2) react with various substituted acetonitriles (3) to give ph osphono-phosphino substituted gamma-thiapyrones (4/5). The constitutio n of one reaction product is confirmed by an X-ray crystal structure a nalysis (4.2 c). The gamma-thiapyrones are converted to boc-protected gamma-thiapyrones (6/7) and to gamma-pyrones (8/9) via oxidation.
