Grosheva, Daria published the artcileKetene Aminal Phosphates: Competent Substrates for Enantioselective Pd(0)-Catalyzed C-H Functionalizations, Computed Properties of 126613-06-7, the publication is ACS Catalysis (2017), 7(11), 7417-7420, database is CAplus.
Nonracemic siloxy- and alkoxybinaphthyl diphenylphospholanes such as I were prepared; in the presence of I, palladium(II) pivalate, pivalic acid, (diarylmethyl)oxodihydropyridinyl phosphates (ketene aminal phosphates) such as II underwent enantioselective C-H activation and cyclization mediated by Cs2CO3 in toluene to yield fused indolizinones such as phenylpyridoisoindolinone III in 59-91% yields and in 73:27-97:3 er. Diaryloxodihydropyridinyl phosphates underwent enantioselective cyclization to give mixtures of regioisomeric products in 88:12-98:2 er and 1.1:1-1.3:1 regioselectivities. The structures of I and of a (chlorophenyl)chloropyridoisoindolinone were determined by X-ray crystallog.
