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 Stereoselective Synthesis of trans-Decalin-Based Spirocarbocycles via Photocyclization of 1,2-Diketones, published in 2021-07-27, which mentions a compound: 16400-32-1, mainly applied to hydroxyl butanone spirocarbocycle preparation diastereoselective DFT crystal structure mol; diketone Norrish Yang photocyclization, SDS of cas: 16400-32-1.
Diastereoselective synthesis of the trans-decalin-based α-hydroxyl butanone spirocarbocycles, e.g., I bearing all-carbon quaternary stereogenic centers was achieved via Norrish-Yang photocyclization of trans-decalin-substituted-2,3-butanediones using daylight. D. functional theory (DFT) calculations suggested that this diastereoselective reaction was affected by both substrate conformation and intramol. hydrogen bonds. The developed chem. could be applied to synthesizing the derivatives of the trans-decalin-based biol. important natural products.
Although many compounds look similar to this compound(16400-32-1)SDS of cas: 16400-32-1, numerous studies have shown that this compound(SMILES:CCC#CCBr), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
