The conjugate addition of aliphatic and aromatic thiols to ethynyl p-tolyl sulphone (tosylacetylene) has been managed to afford Tosvinyl derivatives chemoselectively (in the presence of oxygen nucleophiles) and stereoselectively (isomers Z) in practically quantitative yields. The conditions of choic

A convenient method for the selective hydrogenation of phenolic benzyl ether, Cbz, benzyl ester, nitro and olefin functions distinguishing from the MPM (4-methoxybenzyl) protective group for the phenolic hydroxy groups was accomplished by the addition of pyridine to the PdlC-catalyzed reduction syst
