Therefore, this paper selected the direct oxidation route to synthesize α-isophorone, and according to the principles of green chemistry, oxygen was used as the oxidant, with non-metal N-hydroxy-phthalimide as catalyst, for preparation of Isophorone.

因此本论文的研究选用以α-异佛尔酮直接氧化的路线,且根据绿色化学的原则,以氧气为氧化剂,用一种无金属参与的N–羟基邻苯二甲酰亚胺为催化剂催化α-异佛尔酮,为氧代异佛尔酮的制备提供一条全新的途径。

Firstly, a series of organic molecules which use phthalimido group as electron acceptor, N as electron donor, COO~- as eletrofugal group were synthesized based on SET-promoted photocyclization processes. These compounds were irradiated by 500 W ultraviolet under nitrogen atmosphere in room temperature. After filtration of the photochemical character of these molecules, substrate S1 and S2 were selected as appropriate model reactants. Secondly, the monosubstituted derivatives at the 6-position ofβ-cyclodextrin were synthesized as chiral template of photocyclization.

首先,以单电子转移机理为指导,设计了一系列以邻苯二甲酰亚胺基为电子受体、N为电子给体、羧基为离去基团的光环合反应底物,这些化合物在氮气保护下以500瓦紫外光室温下进行光照反应,对这一系列的分子的反应情况进行了研究与筛选,最终选择底物S1和S2作为研究光环合反应中立体控制方法的模型底物;其次,又合成了一系列6-位单取代β-环糊精,以此作为光环合反应的手性模板。
