treatment with carbon disulphide. The trans-aminoalcohol 7 and its saturated analogue reacted with p-chlorobenzaldehyde to furnish the hexahydro 13 and octahydro-4H-3,1-benzoxazine 13a, respectively. 1H and 13C NMR studies showed that, similarly to the earlier-investigated analogues containing oxygen or unsubstituted nitrogen at position 1, the synthesized cis isomrs 8, 10, 16 and 18 occurred as the preferred
顺式和反式-2-氨基-4-环己烯-1-羧酸1和3与酰亚胺反应,生成稠合骨架的双环顺式和反式嘧啶-4-酮8和9。氨基酸1将3和3还原为顺式和反式1,3-氨基醇6和7,其通过酰亚胺化成双环四氢-4H-3,1-苯并恶嗪10和11,或通过相应的方法被转化。氨基甲酸酯14和15变成四氢4H-3,1-苯并恶嗪-2(1H)-一16和17。2-硫代类似物18和19是通过将氨基醇6和7经处理得到的二硫代氨基甲酸酯环化而制得的与二硫化碳。反式氨基醇7及其饱和类似物与对氯苯甲醛反应,分别得到六氢13和八氢-4H-3,1-苯并恶嗪13a。1 H和13 C NMR研究表明,与早期研究的类似的在位置1处含有氧或未取代氮的类似物一样,合成的顺式同构异构体8、10、16和18以优选的构象异构体的形式出现在N-inside型杂环扭曲反型中。 (准轴C 6 -N键)(B)。在含有饱和C-2原子的反式异构体(13和13a)中,H-2和H-6处于顺式相对位置。

cyclohexene or cyclohexane skeleton were prepared from cis- or trans-2-aminocyclohex-3-enecarboxylic acids in five or six steps through a regio- and stereoselective hydroxylation and hydroxy–fluorine exchange. Fluorinated aminoester enantiomers were synthesized from enantiopure cis- or trans-2-aminocyclohexenecarboxylic acid (prepared byenzymatic resolution of the racemic substances).

By means of total regio- and diastereoselective functionalizations of cis- and trans-2-amino-4-cyclohexenecarboxylic acid derivatives 1, 9, 12 and 16, isomers of 2-amino-4-hydroxycyclohexanecarboxylic acid 8 and 11, and 2-amino-5-hydroxycyclohexanecarboxylic acid 15 and 19 were prepared in good yields, via 1,3-oxazine or γ-lactone intermediates. The enantiomers of 8 and 15 were also prepared by the
