Zhang, Liang published the artcileHydroxymethylation of active methenyl compounds: DMSO as methylene source and H2O as oxygen source, HPLC of Formula: 517-23-7, the publication is Tetrahedron Letters (2022), 153663, database is CAplus.
A mild and efficient method for hydroxymethylation of active methenyl compounds was described. In this transformation, the widely available solvents DMSO and water served as methylene and oxygen sources, resp. Under promotion of activator and base, the reaction could be used for the construction of a series of α-hydroxymethylated carbonyl compounds R1COC(CH2OH)R2R3 [R1 = Me, Ph, Bn, 2-furyl, 2-thienyl; R2 = CN, MeCO, MeO2C, EtO2C, t-BuO2C, PhNHCO; R3 = Me, Et, Bn, etc.; R1R3 = (CH2)3, H2COCH2, (CH2)4, etc.] with all-carbon quaternary carbon center in good to excellent yield.
