Friedel-Crafts Approach to Electron Deficient Cyclic α- Amino Acids
摘要:
An electron deficient 2,2-dimethyl-1-H-phenalene-1,3-dione based cyclic alpha-amino acid was synthesized in 7 steps using Friedel-Crafts acylation as the key step. A new recipe was found to deprotect the required phthalimide protecting group in highly hindered substrates.
