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 Rhodium-Catalyzed Stereoselective Intramolecular [5 + 2] Cycloaddition of 3-Acyloxy 1,4-Enyne and Alkene, published in 2015-10-16, which mentions a compound: 175136-62-6, mainly applied to rhodium catalyzed stereoselective intramol cycloaddition acyloxy enyne alkene; bicyclodecadiene preparation, HPLC of Formula: 175136-62-6.
The first rhodium-catalyzed intramol. [5 + 2] cycloaddition of 3-acyloxy 1,4-enyne and alkene was developed [e.g., I → II (91%, 80% isolated) in presence of [Rh(cod)Cl]2 and [3,5-(CF3)2C6H3]3P]. The cycloaddition is highly diastereoselective in most cases. Various cis-fused bicyclo[5.3.0]decadienes were prepared stereoselectively. The chirality in the propargylic ester starting materials could be transferred to the bicyclic products with high efficiency. Electron-deficient phosphine ligand greatly facilitated the cycloaddition Up to three new stereogenic centers could be generated. The resulting diene in the products could be hydrolyzed to enones, which allowed the introduction of more functional groups to the seven-membered ring.
From this literature《Rhodium-Catalyzed Stereoselective Intramolecular [5 + 2] Cycloaddition of 3-Acyloxy 1,4-Enyne and Alkene》,we know some information about this compound(175136-62-6)HPLC of Formula: 175136-62-6, but this is not all information, there are many literatures related to this compound(175136-62-6).
