Abstract A mild and green photo-organocatalytic protocol for the highly efficient acetalization of aldehydes has been developed. Utilizing thioxanthenone as the photocatalyst and inexpensive household lamps as the light source, a variety of aromatic and aliphatic aldehydes have been converted into acyclic and cyclic acetals in high yields. The reaction mechanism was extensively studied Photo-organocatalytic synthesis of acetals from aldehydes   Nikolaos F. Nikitas,a  Ierasia Triandafillidia  and  Christoforos G.

Endo-4,7-bis(hydroxymethyl)hexahydro-1H-4,7-epoxyisoindole-1,3(2H)-dione (endo-4,7- bis(hydroxymethyl)norcantharimide), 4 (method A) Endo-4,7-bis(hydroxymethyl)norcantharimid-5-ene (120 mg, 0.53 mmol) was dissolved in water (3 mL), Pd/C 10% was added (15 mg) and reaction mixture was placed under hydrogen atmosphere for 8 h at 24 °C. Catalyst was filtered off and washed thoroughly with water (3 × 3 mL), filtrate was evaporated under reduced pressure. Target compound 4 was obtained as white solid, yield 87% (110 mg). 1H NMR (D2O) = 3.76 (s, 4H), 3.46 (s, 2H), 1.61-1.72 (m, 4H); 1H ..read more
