Regiocontrolled dieckmann condensation of 3,4-Bis(methoxycarbonylmethyl) levoglucosenone derivative
摘要:
The Dieckmann condensation of 3,4-bis(methoxycarbonylmethyl) levoglucosenone derivative afforded two regioisomeric 9,11-dioxatricyclo[6.2.1.0(2,6)]undecane derivatives at a ratio of 5: 3. The products can be used in the synthesis of iridoids.
