Oxidative 3,3,3-trifluoropropylation of arylaldehydes

Synthesis of New C2-Symmetric Six-Membered NHCs and Their Application for the Asymmetric Diethylzinc Addition of Arylaldehydes

A concise method for the preparation of new 3,4,5,6-tetrahydropyrimidinium salts was presented in this paper. Further application of these salts in asymmetric diethylzinc addition of arylaldehydes was explored, giving the corresponding chiral second alcohols in good yields and moderate enantioselectivities.

Synthesis of Novel Indane-1,3-dione Derivatives and Their Biological Evaluation as Anticoagulant Agents

2-Substituted derivatives of indane-1,3-dione 3a–f , 5a–g, 6a–g were synthesized and investigated as anticoagulant agents. 2-Arylindane-1,3-diones (3) were obtained in the reaction of phthalide with appropriate arylaldehydes. 2-Arylmethyleneindane-1,3-diones (5) were prepared by condensation of indane-1,3-dione with the corresponding arylaldehydes. The compounds 5 were converted into their meth...

Synthesis and Identification of SO3H-functionalized Phthalimide (SFP) as an Efficient Catalyst for the Condensation of Dimedone with Arylaldehydes

A SO3 H-containing solid acid namely SO3 H-functionalized phthalimide (SFP) was synthesized from phthalimide and chlorosulfonic acid, and identified by studying its FT-IR, 1 H and 13C NMR, Mass, XRD, TG and DTG spectra. Afterward, its catalytic activity was examined for the solvent-free condensation of dimedone (5,5-dimethyl-1,3-cyclohexanedione) (2 eq.) with arylaldehydes (1 eq.). The results ...

Preparation, characterization and the use of sulfonic acid-functionalized phthalimide (SFP) as a highly efficient and green catalyst for the condensation of arylaldehydes with 2-naphthol

Phthalimide was reacted with chlorosulfonic acid to give sulfonic acid-functionalized phthalimide (SFP), which characterized by 1H NMR, 13C NMR, FT-IR, XRD (X-ray diffraction), SEM (scanning electron microscopy), EDX (energy-dispersive X-ray), mass, TG (thermogravimetry) and DTG (derivative thermal gravimetry) spectra. Afterward, its catalytic activity was examined for the condensation of aryla...
