So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Chen, Sijia; Zhang, Zhongchao; Jiang, Chongguo; Zhao, Chunbo; Luo, Haojie; Huang, Jun; Yang, Zhen researched the compound: 1-Bromo-2-pentyne( cas:16400-32-1 ).Related Products of 16400-32-1.They published the article 《Stereoselective Synthesis of trans-Decalin-Based Spirocarbocycles via Photocyclization of 1,2-Diketones》 about this compound( cas:16400-32-1 ) in ACS Omega. Keywords: hydroxyl butanone spirocarbocycle preparation diastereoselective DFT crystal structure mol; diketone Norrish Yang photocyclization. We’ll tell you more about this compound (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.
