  Synthesis of (±)-coerulescine and a formal synthesis of (±)-horsfiline

  摘要：

  A straightforward synthesis of (+/-)-coerulescine and (+/-)-horsfiline has been established from 3-formyl-3-phenylpyrridine employing 4-hydroxypiperidine as the starting material. There are two remarkable steps for the synthesis of (+/-)-coerulescine and ()-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-plienylpyrrolidine to the 3,3-spirocyclic 2-oxindole ring skeleton. (c) 2005 Elsevier Ltd.
