Ramesh, Balu published the artcileRu(II)- or Rh(III)-Catalyzed Annulation of Aromatic/Vinylic Acids with Alkylidenecyclopropanes via C-H Activation, Name: 2-Methylbenzoic acid, the publication is Journal of Organic Chemistry (2022), 87(9), 5668-5681, database is CAplus and MEDLINE.
An efficient and new route for the synthesis of (E)-4-benzylideneisochroman-1-ones I [R1 = 6-Me, 7-Cl, 8-MeO, etc.; Ar = Ph, 4-ClC6H4, 3-BrC6H4, etc.] through tandem cascade annulation of benzoic acids with alkylidenecyclopropanes using Ru(II) as a catalyst was demonstrated. It was important to note that the reaction delivers selectively E-stereoselective 4-benzylideneisochroman-1-one derivatives in moderate to good yields, which had completely diverse selectivity as compared with previous methods. Further, the annulation was explored with less-reactive ¦Â C-H activation of vinylic acids with alkylidenecyclopropanes, leading to the highly useful ¦Á-pyrone derivatives II [R3 = Me, CF3, Ph, Bn; Ar= Ph, 3-MeC6H4, 4-ClC6H4, 4-BrC6H4] in the presence of an Rh(III) catalyst.
