The synthetic utility of this protocol was carried out with syn-isomer to yield corresponding cis-aziridines. This protocol was operationally simple for a wide variety of substituted carboxaldehydes and substituted phenacyl bromides.

By fusing methyl picolinate with phenacyl bromides, the corresponding phenacyl salts were obtained, cyclization of which in acetic anhydride led to previously undescribed 3-aryl-1H-pyrido[2,1-c][1,4]oxazinium bromides. Reduction of the quaternary salts of methyl picolinate followed by acid hydrolysis leads to the alkaloid DL-baikiain.

Our study is about carrying out indium-mediated allylation reactions of phenacyl bromides in aqueous solution that form homoallytic bromohydrins We can get high yields and functional tolerance in our method. Homoallylic broniohydrins should be useful in organic synthesis. In our study by employing subsequent base treatment, the homoallylic bromohydrins were converted to allyhc epoxides.

Abstract:
In this abstract is being discussed the synthesis of new substituted amides of dehydroabietic acid with different bromides in system K2CO3/DMF. It is known fact that many compounds, such as famous isatine 1, have the amide group in its molecule. There is no point in talking about it, because everything is known regarding chemical properties. However, what if there are two amide groups in the molecule at once? Let us see… For our investigation, we used the model of well-known alkylation reaction [1]. As starting material, we used two types of bromide: aliphatic and aromatic – bromoacetone [2] a
