Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 16400-32-1, is researched, Molecular C5H7Br, about Stereoselective Synthesis of trans-Decalin-Based Spirocarbocycles via Photocyclization of 1,2-Diketones, the main research direction is hydroxyl butanone spirocarbocycle preparation diastereoselective DFT crystal structure mol; diketone Norrish Yang photocyclization.Product Details of 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.
