Ihara, Masataka published the artcileStereoselective total synthesis of (¡À)-3-oxosilphinene through intramolecular Diels-Alder reaction, Name: Allyldiphenylphosphine oxide, the publication is Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) (1987), 1331-7, database is CAplus.
The angular tricyclopentanoid sesquiterpene (¡À)-3-oxosilphinene (I) was stereoselectively prepared with an intramol. Diels-Alder reaction as the key step. On heating, the (E,E)-sulfenyltriene II (R = CHMeCH2CH2CH:CHCH:CHSPh), derived from II (R = Br) gave only 1 stereoisomer of tricyclo[7.3.0.01.5]dodecene III having all 4 contiguous asym. centers with the required stereochem. The cycloadduct III was converted into the racemate of I via ring contraction.
Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) published new progress about 4141-48-4. 4141-48-4 belongs to catalysis-chemistry, auxiliary class Aryl phosphine ligand,Mono-phosphine Ligands, name is Allyldiphenylphosphine oxide, and the molecular formula is C15H15OP, Name: Allyldiphenylphosphine oxide.
