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.
