An efficient isocyanide-based synthesis of S-thiocarbamates was discovered and thoroughly investigated. The new reaction protocol is a one-pot procedure allows the direct conversion N-formamides into thiocarbamates by initial dehydration with p-toluene sulfonyl chloride to respective isocyanide subsequent addition sulfoxide component. Contrary recent literature, which also uses isocyanides as s...

(-)-Ambrox is recognised as the prototype of all ambergris odorants. Widely used in perfumery, (-)-Ambrox is an important ingredient due to its unique scent and excellent fixative function. An environmentally friendly and practical preparation of (-)-Ambrox is still unavailable at present although a lot of attention has been paid to this hot research topic for many years. A one-pot synthesis of...

a facile and efficient one-pot three-step process for the synthesis of 5-acetyl-2-imino-4-methylthiazoles via the cyclocondensation of 3-thiocyanatoacetylacetone with various hydrazine or hydrazide derivatives in etoh has been developed. 3-thiocyanatoacetylacetone itself has been synthesized as the intermediate from substitution reaction of thiocyanate with 3-chloroacetylacetone. better results...

the one pot reaction of glyoxal and hydroxylamine hydrochloride in aqueous sodium hydroxide was found to be a safe and inexpensive method for the preparation of diaminoglyoxime. by increasing stoichiometric ratio of the hydroxylamine hydrochloride and decreasing the solvent volume, the product yield increased considerably (~ 70%).
