近幾十年來,天然物的雜環結構越來越受到重視,許多有機化學家紛紛投入此領域中,提出各種雜環化合物的合成研究。
本實驗室主要探討硫烷基醯胺化合物的環化反應,我們利用醋酸錳(Manganese(III) acetate)和醋酸銅(Copper(II) acetate),促使
硫烷基醯胺化合物進行親電性環合反應,成功的合成出Isatins化合物及Oxindoles化合物。
本論文將分為兩部分:
第一部分: N-乙烷基-N-苯基單-硫烷基醯胺化合物與醋酸銅(II)的離子性環合反應 (式1)。
第二部分: N-乙烷基-N-苯基雙-硫烷基醯胺化合物與醋酸錳(III)及醋酸銅(II)的環合反應(式2)。
Compounds containing a heterocyclic ring represent an important class of biologically active molecules that are widespread
in nature.Organic chemists have reported many methods for the preparation of these compounds. In our laboratory, we are
interested in the cyclization reactions of alkythio substituted aromatic amide derivatives by using manganese (III) acetate and
copper (II) acetate. We successfully synthesized the Isatin and Oxindole compounds,by these methods.
In this thesis,our studies on the following reaction will be described:
(1). The ionic cyclization reactions of N-ethyl- 2-methylsulfanyl-N-phenyl-acetamide mediated by copper (II) acetate.(eq. 1)
(2). The cyclization reactions of 2,2-bismethylsulfanyl-N-ethyl- N-phenyl acetamide mediated by manganese (III) acetate and copper (II) acetate.(eq. 2)
