gem-alkoxycarbonylnitroethenes with cyclic β-diketones (dihydroresorcinol and dimedone) occurs as a one-pot process via sequential AdN and SN steps followed by denitration to give functionally substituted hexahydrobenzofurans. The intermediate products of the nucleophilic addition have been isolated in the reactions of gem-acetylnitroethenes with dihydroresorcinol. The structures of the synthesized compounds
宝石-苯甲酰基硝基乙烯和宝石-烷氧基羰基硝基乙烯与环状β-二酮(二氢间苯二酚和二甲酮)的相互作用是通过顺序的Ad N和S N步骤进行一锅法过程,然后进行反硝化生成功能取代的六氢苯并呋喃。亲核加成的中间产物已经在宝石-乙酰基硝基乙烯与二氢间苯二酚的反应中分离出。合成化合物的结构已通过IR,1 H和13 C- 1 H}光谱学证实,其中包括异核相关实验(1 H- 13 C HMQC和1 H- 13 C HMBC)。

beta-Acetyl- and beta-benzoyl-beta-nitrostyrenes reacted with benzenethiols under mild conditions to give previously unknown 4-aryl-4-(arylsulfanyl)-3-nitrobutan-2-ones and 3-aryl-3-(arylsulfanyl)-2-nitro-1-phenylpropan-1-ones, respectively, which were isolated as pure diastereoisomers or mixtures of two diastereoisomers.

The synthesis of previously unknown 2,3- and 2,5-dihydro-1,5-benzothiazepines sontaining nitro group was performed by the easy sondensation of geminal acylnitrostyrenes with the o-aminothiophenol. The structure of the obtained sompounds was studied by physicochemical methods. By X-ray diffraction analysis the geometry and structural parameters of 4-methyl-3-nitro-2-phenyl-2,3-dihydro-1,5-benzothiazepine were determined.

Reactions of 2-aryl(heteryl)-1-acetyl(benzoyl)-1-nitroethenes with 2,3-dimethyl-1,3-butadiene led to the formation of products of [4+2]-cycloaddition, 1-acyl-6-aryl(heteryl)-3,4-dimethyl-1-nitro-3-cyclohexenes. Their structure was proved by IR and H-1 NMR spectroscopy.
