2-arylhydrazonopropanals 3a-c to yield polyfunctionallysubstituted azolylarylazophenols 5 and 8. The reaction of 1b and 2 with phenylisothiocyanate in the presence of α-haloketones afforded the azolylthiophenes 12a,b and 13a,b. The reaction of 20 with α-haloketone afforded 5-benzotriazol-1-yl-6-methyl-2-(2-oxopropylsulfanyl)nicotinonitrile 21 that was utilized as buildingblocks for the synthesis of condensed
标题化合物1a-b和2与2-芳基肼基丙醛3a-c反应,得到多官能取代的偶氮基芳基偶氮苯酚5和8。1b和2与苯基异硫氰酸酯在α-卤代酮存在下反应,得到偶氮基噻吩12a,b和13a,b。 。20与α-卤代酮的反应提供了5-苯并三唑-1-基-6-甲基-2-(2-氧丙基硫基)烟腈21,其被用作合成缩合吡啶的结构单元。将化合物21与二甲基甲酰胺二甲基缩醛缩合,得到噻吩并[2,3 - b ]吡啶-3-基-N,N-二甲基甲am衍生物22。将其进一步用氢化钠环化成1 H-二硫代[2,3- b]。4,5- b'] dipyridin-4-one衍生物23。

Compounds of formula I:
or salts thereof are disclosed. Also disclosed are pharmaceutical compositions comprising a compound of formula I, processes for preparing compounds of formula I, intermediates useful for preparing compounds of formula I and therapeutic methods for treating a Retroviridae viral infection including an infection caused by the HIV virus.
To find an antifungal agent other than those of the imidazole and triazole series, a new class of 1,2-disubstituted propenones I and II was prepared and tested for antifungal activity. Comparison of the structure-activity relationships showed that the conjugated structure of carbonyl and exomethylene groups in I and II plays an important role in potent antifungal activity. However, it is noteworthy that compounds 53, 54, and 56, which have a hydroxymethyl or methoxymethyl group instead of an exo-methylene group in I, also showed potent activity. Although many compounds exhibited strong antifungal activity in vitro, none showed activity in vivo of oral efficacy against subacute systemic candidiasis in mice.
