The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: (R)-4-(tert-Butyl)-2-(5-(trifluoromethyl)pyridin-2-yl)-4,5-dihydrooxazole( cas:1428537-19-2 ) is researched.Related Products of 1428537-19-2.Allen, Jamie R.; Bahamonde, Ana; Furukawa, Yukino; Sigman, Matthew S. published the article 《Enantioselective N-Alkylation of Indoles via an Intermolecular Aza-Wacker-Type Reaction》 about this compound( cas:1428537-19-2 ) in Journal of the American Chemical Society. Keywords: indolylalkanal chemoselective enantioselective preparation; chemoselective enantioselective aza Wacker reaction allylic homoallylic alc indole; enantioselective alkylation indole allylic homoallylic alc palladium catalyst; stereochem mechanism aza Wacker reaction deuterated allylic alc indole. Let’s learn more about this compound (cas:1428537-19-2).
In the presence of Pd(MeCN)2(OTs)2 and a nonracemic pyridinyloxazoline, 3-substituted indoles such as 3-phenylindole underwent intermol., chemoselective, and enantioselective alkylation/aza-Wacker reactions with cis-allylic and cis-homoallylic alcs. such as (Z)-EtCH:CHCH2OH mediated by p-benzoquinone in 1,2-dichloroethane to yield nonracemic β- and γ-(1-indolyl)alkanals such as I; enamines generated under other conditions were not formed. The mechanism was studied using the reaction of a deuterium-labeled allylic alc.; the stereochem. of the product supported a syn amino-palladation mechanism for the reaction.
