Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Safety of (S)-4-(tert-Butyl)-2-(4-(trifluoromethyl)pyridin-2-yl)-4,5-dihydrooxazole

Synthetic studies towards the mannolides: Construction of the bowl-shaped B/C/D ring system was written by Wang, Kunkai;Xu, Zhezhe;Tan, Xiangchuang;Xie, Zhixiang. And the article was included in Tetrahedron in 2020.Safety of (S)-4-(tert-Butyl)-2-(4-(trifluoromethyl)pyridin-2-yl)-4,5-dihydrooxazole This article mentions the following:

The bowl-shaped tricyclo[6.3.1.04,12]dodecane moiety is the core feature of cephalotane-type diterpenoids. As part of our efforts directed towards a total synthesis of mannolide B, the bowl-shaped tricyclo[6.3.1.04,12]dodecane skeleton, a common intermediate of cephalotane-type diterpenoids bearing up to five contiguous stereocenters including two quaternary carbon centers had been constructed. The synthetic strategy was enabled by an efficient application of oxidative dearomatization/intramol. Diels-Alder reaction to access highly functionalized building block with the tricyclo[5.2.2.02,6]undecane unit from com. available materials. The key feature was firstly used the cyclic olefins with secondary alc. as dienophile for the intramol. inverse electron demand Diels-Alder reaction. Further synthetic studies led to construct ring D by a regioselective Aldol reaction. In the experiment, the researchers used many compounds, for example, (S)-4-(tert-Butyl)-2-(4-(trifluoromethyl)pyridin-2-yl)-4,5-dihydrooxazole (cas: 1257527-14-2Safety of (S)-4-(tert-Butyl)-2-(4-(trifluoromethyl)pyridin-2-yl)-4,5-dihydrooxazole).
