In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis of Multifunctional Alkenes from Substituted Acrylates and Aldehydes via Phosphine-Catalyzed Wittig Reaction, published in 2015, which mentions a compound: 707-61-9, mainly applied to alkene ethoxycarbonyl aroylmethyl diastereoselective preparation; aldehyde diastereoselective Wittig reaction aroyl acrylate phosphine catalyst, Reference of 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide.
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.
Here is just a brief introduction to this compound(707-61-9)Reference of 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide, more information about the compound(4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide) is in the article, you can click the link below.
