Regioselective Alkylation in the Course of Aldol Condensation under Phase-Transfer Catalytic Conditions

Article abstract of DOI:10.1246/bcsj.61.2256

Regio- and stereoselective alkylation in the course of aldol condensation under liquid-solid phase-transfer catalytic conditions, affording conjugated dienyl ether (5) or α-substituted β,γ-olefinic aldehyde (7) depending on the starting halides, both in good yields, was disclosed.The reaction mechanism is also discussed.
