dc.description.abstract | ÖZET Tersiyer fenilasetamidler aynı kapta sodyum veya potasyum borhidrür beraberinde, karşılık gelen aromatik aldehid, amin ve arilasetil klorürden elde edildiler. Oluşan ürünler kurşun tetraasetat ile O-asetümandelamid türevlerine dönüştürüldüler. Amidden O-asetilmandelamidi veren reaksiyon sadece aril halkasında elektron salan gruplara sahip olan amidlerle gerçekleştirildi, O-Asetilmandelamid türevleri, proton veya Lewis asidleri ile 1,2,3,4- tetrahidroizokinolin-3-on'lara dönüştürüldüler. N,N-Disübstitüe fenilasetamidler oksidleyici olarak kurşun tetraasetat asetik asid trifluorasetik asid karışımında kullanılarak doğrudan 1,2,3,4-tetrahidroizokinolin-3-on lara dönüştürüldüler. A -îmidazolin-N-oksidler, karşılık gelen aromatik Schiff bazları ile syn-2- bromoasetofenon oksimin reaksiyonundan elde edildiler. Bazı örneklerde 5,6-dihidro- 4H-1,2,5-oksadiazinler de yan ürün olarak izole edildiler. | |
dc.description.abstract | ABSTRACT Tertiary phenylacetamides were prepared from the corresponding aromatic aldehydes, amines and arylacetyl chlorides in the presence of sodium or potassium borohydride, as a on pot reaction. The resulting compounds were converted into O- acetylmandelamide derivatives with lead tetraacetate. The reaction from amide to O-acetilmandelamide proceeds only with amides having electrondonating groups at the aryl ring. O-Acetylmandelamide derivatives were converted into 1,2,3,4- tetrahydroisoquinolin-3-ones in the presence of protonic or Lewis acids. Some of the N,N-disubstituted phenylacetamides were converted directly into 1,2,3,4- tetrahydroisoquinolin-3-ones in the presence of lead tetraacetate as oxidant in the mixture of acetic acid and trifluoroacetic acid. 3 A -Imidazolin-N-oxides were prepared by the reaction of corresponding aromatic Schiff bases with syn-2-bromoacetophenone oxime. 5,6-Dihydro-4H-l,2,5-oxadiazines were also isolated as byproduct in some instances. | en_US |
