Name: 1-Bromo-2-pentyne. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 1-Bromo-2-pentyne, is researched, Molecular C5H7Br, CAS is 16400-32-1, about Stereoselective Synthesis of trans-Decalin-Based Spirocarbocycles via Photocyclization of 1,2-Diketones. Author is Chen, Sijia; Zhang, Zhongchao; Jiang, Chongguo; Zhao, Chunbo; Luo, Haojie; Huang, Jun; Yang, Zhen.
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.
After consulting a lot of data, we found that this compound(16400-32-1)Name: 1-Bromo-2-pentyne can be used in many types of reactions. And in most cases, this compound has more advantages.
