Webb1 okt. 2024 · A simple one-pot approach was developed for the synthesis of furan-2(5H)-one derivative containing indole fragments. This method includes the telescoped multicomponent reaction of indole, 4-methoxyphenylglyoxal, and Meldrum’s acid. The synthetic utility of the prepared furan-2(5H)-one was demonstrated by condensation with … WebbGroupe: Poste de tra va il: Obje ct if s de l’e xercice. 1. ... 3. ap p rovis ion n em e n t, m an u te n tion, c ontr ôle, n ett oy ag e, m ai n ten a n c e, en tr e tie n, c ha n g e m en t de pi ...

Webbgocphim.net WebbWith the Rovis group, we recently reported the C−OH activation of carboxylic acids using phosphines and photoredox catalysis (Figure 1C).10 This work demonstrated that nucleophilic trapping of a phosphine radical cation could be leveraged to release acyl radicals via β-scission from a proposed phosphoranyl radical.11 We showed that the … change image on hover javascript

Webb19 juni 2024 · The Rovis group also published a short synthetic route for the synthesis of (−)-paroxetine in just six steps, beginning with sesamol (12) (Scheme 4) [14]. The key step in their approach was an asymmetric NHC-catalyzed conjugate addition reaction of enal 8 on nitroalkene 14 followed by an in situ reductive cyclization to generate lactam 15 [ 15 ].
