A Rh(I)-catalyzed intermolecular cyclization between isocyanates and benzocyclobutenols leading to isoquinolin-1(2 H)-ones through selective cleavage of a C-C bond has been realized. Exploiting the same strategy, we developed three-component reaction benzocyclobutenols, isonitriles, sulfonyl azides access H)-imines. These procedures provide unique expeditious isoquinolone derivatives which are otherwise difficult prepare in satisfactory yields with excellent functional-group tolerance under...
We disclose herein the oxidative dehydrogenation performance of a Lindquist-type polyoxomolybdate, [N(C4H9)4]2[Mo6O19], with irradiation visible light. The formulated inorganic molecular Mo6 photocatalyst can facilitate, high efficiency, cross-dehydrogenative coupling P(O)H compounds and thiols in water ambient oxygen as oxidant. Moreover, gram-scale reaction smoothly proceed under simple, low catalyst loading system turnover numbers. This exhibited good stability reusability after at least...
Abstract A Pd‐catalyzed regio‐ and stereoselective alkynylallylation of a specific C−C σ bond in cyclopropenes, using allyl propiolates as both allylation alkynylation reagents, has been achieved for the first time. By merging selective C(sp 2 )‐C(sp 3 ) scission with conjunctive cross‐couplings, this decarboxylative reorganization reaction features fascinating atom step economy provides an efficient approach to highly functionalized dienynes from readily available substrates. Without...
Visible-light-induced C(sp 2 )–H phosphorylation of H -thiozoles/quinoxalines with H-phosphine oxides was achieved using an inorganic ligand-supported Mo oxide ([N(C 4 9 ) ] [Mo 6 O 19 ]) as a hydrogen atom transfer (HAT) photocatalyst.
We herein report a direct and efficient protocol for phosphorylation of quinoxalines, which employs aerobic oxygen as the green oxidant under catalyst-free conditions. This methodology represents one most environmentally friendly easily handled protocols, providing series phosphorylated quinoxalines in good to excellent yields. Control experiments clearly indicated that reaction followed dearomatization-rearomatization strategy.
