Solvent effects on stereoselectivity in 2,3-dimethyl-4-chromanone cyclization by quinine-catalyzed asymmetric intramolecular oxo-Michael addition
Tanaka, Tomohiro,Kumamoto, Takuya,Ishikawa, Tsutomu
, p. 4633 - 4637 (2000)
Examination of the quinine-catalyzed asymmetric intramolecular oxo-Michael addition of o-tigloylphenol in various solvents led to high stereoselectivity in chromanone cyclization when chlorobenzene was used as a solvent, giving cis-2,3-dimethyl-4-chromano
Intermolecular C-O addition of carboxylic acids to arynes: Synthesis of o-hydroxyaryl ketones, xanthones, 4-chromanones, and flavones
