"In Ke Kong's journal article, Kong explains his ambition to discover an enantiosynthesis of the spirocyclic imine (-)-gymnodimine (a marine toxin) in order to provide modern antigens to monitor and eliminate it. Preliminary trials to promote this Diels-Alder enantioselective reaction failed with the diene (Z)-silylenol ether due to a lack of reactivity, even in the presence of chiral catalysts. This failed reactivity was most likely attributed to geometrical issues so the synthesis of the diene (E)-silylenol ether (which is our product 24) was pursued. In the first step for (E)-silylenol ether's synthesis, (E)-vinyl stannane was used as a starting material rather than other radical and metal-catalyzed hydrostannylations because its regioselectivity was more stable and therefore formed the final (E)- silylenol ether. (E)-vinyl stannane goes through tin-lithium exchange with n-BuLi followed by a reaction with the amide N-methyl-N-methoxyacetamide in order to form the ketone (which is our intermediate S-6). This essentially describes the first step for the formation of (E)- silylenol ether; the ketone continues through enolization and silyation to form (E)- silylenol ether.

This article cited the article by Kong as a preview to their report. This article’s research consists of reporting a straightforward approach to the tetrahydrofuran core, gymnodimine, using the Ueno-Stork reaction as a key-step, but cites the first article in order to show that other approaches of synthesizing gymnodimine have already been reported.

This article was further research into the synthesis of (-)-Gymnodimine, the marine toxin that was being researched in the previous article.  While the 2005 article only managed to synthesize a spirocyclic imine intermediate, a full synthesis for the compound was proposed in this article.

In this article, research was done into the yields and diastereoselectivity of various copper catalyzed Diels-Alder reactions. The article refers to the Diels-Alder reaction of the six-membered cyclic imide and diene catalyzed by Cu(SbF6)2 that is used in the Kong article with high diastereoselectivity and yield.
