Compound: 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide, is researched, Molecular C11H13OP, CAS is 707-61-9, about Synthesis of Multifunctional Alkenes from Substituted Acrylates and Aldehydes via Phosphine-Catalyzed Wittig Reaction, the main research direction is alkene ethoxycarbonyl aroylmethyl diastereoselective preparation; aldehyde diastereoselective Wittig reaction aroyl acrylate phosphine catalyst.SDS of cas: 707-61-9.
An efficient synthesis of multifunctional alkenes (E)-R1C(O)CH2C(CO2Et):CHR2 (R1 = Me, Ph, 4-O2NC6H4, 2-thienyl, 2-naphthyl, etc.; R2 = Ph, 3-O2NC6H4, 2-furyl, 4-pyridinyl, etc.) starting from substituted acrylates (E)-R1C(O)CH:CHCO2Et and aldehydes R2CHO has been developed via phosphine-catalyzed Wittig reactions. The reactions proceed smoothly even under mild conditions (30-60 °C) via a phosphine/phosphine oxide catalytic cycle using phenylsilane as the reducing agent. According to this simple protocol, the desired products are obtained in moderate to excellent yields as single stereoisomers.
