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 Highly Enantioselective Rhodium-Catalyzed Cross-Addition of Silylacetylenes to Cyclohexadienone-Tethered Internal Alkynes, published in 2019-03-15, which mentions a compound: 36620-11-8, mainly applied to enantioselective rhodium catalyst cross addition silylacetylene cyclohexadienone internal alkyne; regioselective stereoselective cross addition, HPLC of Formula: 36620-11-8.
The first highly enantioselective rhodium-catalyzed cross-addition of silylacetylenes to cyclohexadienone-tethered internal alkynes has been achieved via a tandem process: regioselective alkynylation of the internal alkynes and subsequent intramol. conjugate addition to the cyclohexadienones, affording the cis-hydrobenzofuran frameworks with good yields (up to 88% yield) and excellent enantioselectivities (90%-96% ee). This mild reaction showed perfect atom economy and broad functional group tolerance. Furthermore, a gram-scale experiment and diverse further conversions of the cyclization products were also presented.
Compound(36620-11-8)HPLC of Formula: 36620-11-8 received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(Bis(norbornadiene)rhodium (I) tetrafluoroborate), if you are interested, you can check out my other related articles.
