A highly efficient synthesis of chiral 3,3-disubstituted oxindoles was developed by using a chiral spirocyclic phosphoric acid catalyzed 1,6-conjugate addition reaction of para-quinone methoids derived from N-unprotected isatins with indoles. The reaction proceeds under mild reaction conditions to p more
The catalytic pyrolysis of carbohydrates over phosphoric acid-activated carbon catalyst (ACC) was investigated to obtain phenol-rich bio-oil and syngas production in a facile fixed-bed reactor for the first time. A central composite experimental design (CCD) was used to optimize the reaction conditi more
