King, Frank D.; Aliev, Abil E.; Caddick, Stephen; Tocher, D. A. published the artcile< A novel synthesis of (di)-benzazocinones via an endocyclic N-acyliminium ion cyclization>, Category: ethers-buliding-blocks, the main research area is benzazocinone preparation; acyliminium cyclization.
The triflic acid-mediated endocyclic N-acyliminium ion cyclization provides a facile synthesis of (di)-benzazocinones, e.g. I (R = H, 14-Cl, 15-Br, etc.). On reduction of the 10-Ph derivative, an unusually nonpolar tertiary alkylamine II was obtained.
Organic & Biomolecular Chemistry published new progress about Cyclization. 52244-70-9 belongs to class ethers-buliding-blocks, and the molecular formula is C11H16O2, Category: ethers-buliding-blocks.
