Synthesis of (¡À)-coerulescine and a formal synthesis of (¡À)-horsfiline

A straightforward synthesis of (¡À)-coerulescine and (¡À)-horsfiline has been established from 3-formyl-3-phenylpyrrolidine employing 4-hydroxypiperidine as the starting material. There are two remarkable steps for the synthesis of (¡À)-coerulescine and (¡À)-horsfiline. One is the rapid access to produce 3-formyl-3-phenylpyrrolidine by Lewis acid-catalyzed rearrangement of 3,4-dihydroxy-4-phenylpiperidine. The other key step is an intramolecular electrophilic cyclization from 3-benzylcarbamoyl-3- phenylpyrrolidine to the 3,3-spirocyclic 2-oxindole ring skeleton.
