Ultrasound-assisted Wittig reaction and synthesis of 5-alkyl- and 5-alkenyl-resorcinols

Some 5-alkyl- and 5-alkenyl-resorcinols were synthesised from commercially available 3,5-bis(benzylo×y)benzaldehyde by ultrasound-assisted Wittig reaction with alkyltriphenyl phosphonium bromides in basic aqueous condition, followed by debenzylation and simultaneously reduction of a double bond of the styrene type with Na/n-BuOH in overall yields of 62-72%.

Synthesis of ardisinol II

The first and also a concise synthesis of ardisinol II by two routes in excellent yields are described.
