2-acetylamino-l

Electrophiles react with 2-substituted 1,3-selenazoles at the 5-position. Nitration of 2-alkyl-l,3-selenazoles and 2-acetylamino-l,2-selenazole affords 5-nitroderiva-... 

An alternative process is described in US Patent 2,980,679 as follows. 15 grams of finely powdered 2-acetylamino-l,3,4-thiadiazole-5-mercaptain are suspended in 200 ml of water containing 4 grams of potassium bromide. From... 

A mixture of 50 parts by weight of racemic 2-acetylamino-l-(4-methylmercaptophenyl)-l,3-propanediol, 100 parts by weight of concentrated hydrochloric acid, and 500 parts by weight of water was warmed on a steam bath for thirty minutes. The resulting solution was cooled to about 40°C and was then made strongly alkaline by addition of 35% aqueous sodium hydroxide solution. The alkaline solution was then refrigerated. The white solid which separated from the cooled solution was collected on a filter. There was thus obtained 27 parts by weight of 2-amino-l-(4-methylmercaptophenyl)-1,3-propanediol. This product melted at 130.7°C to 131.9°C after recrystallization from methanol. 

The 2-acetylamino-l,3-benzenetellurols required as the precursors of 1,3-benzotellur-azoles, can be prepared from tellurium tetrachloride and 2-aminophenyl mercury chlorides. This method allows the synthesis of 1,3-benzotellurazoles with substituents in the para-position to the nitrogen atom2.

Potassium selenocyanate in acetic anhydride reacts with epoxides to give 2-acetylamino-l,3-oxaselenole derivatives <93JCS(P2)35l>. Low yields of 1,3-oxaselenoles are obtained in the reaction of selenium with ethyne in aqueous base <89ZOR2283). 

Amino-l,2-dihydroacronycine (40 ) could be easily converted into variously substituted amines and amides. Treatment of 40 with formaldehyde and sodium borohydride afforded 2-dimethylamino-l,2-dihydroacronycine (42). Both aliphatic and aromatic amides were obtained from 4 upon treatment with acid anhydrides in pyridine. This latter reaction is exemplified by the preparation of 2-acetylamino-l,2-dihydroacronycine (43J and 2-benzoylamino-l,2-dihydroacronycine (44) using acetic anhydride and benzoic anhydride, respectively (53).
