Polarized ethylenes having both electron-donating (an amino or a methylthio group) and electron-accepting (cyano, carbamoyl, methyl ester) groups on the adjacent two olefinic carbon atoms were prepared by the condensation of S-alkylthioamidinium salts or

Several unnatural pyrazole and 1,2,4-triazole nucleosides are synthesized in a regio- and stereoselective manner by the reaction of readily available ketene dithioacetals with 1-ribofuranosylhydrazine.
