Fluorapatite: An Effective Solid Base Catalyst for Michael Addition of Indole/pyrrole to Nitroalkenes under Solventless
Solid base fluorapatite was found to catalyze the Michael addition of indole/pyrrole to nitroalkenes efficiently under solventless condition, affording the products in good to excellent yields. The Michael addition occurred at the 3-position of indole exclusively with an exception of 3-methylindole. The synthetic fluorapatite could be recovered and reused easily without obvious loss in activity.
