Total synthesis of (±)-2-pupukeanone
Chang, Nein-Chen,Chang, Chi-Kang
, p. 4967 - 4970 (1996)
A synthesis of (±)-2-pupukeanone (4) is described in which the pupukeanane skeleton is assembled by means of intramolecular cyclization of tosylate 11 and then the attachment of an isopropyl group at the appropriate position of the tricyclic ring system. The key intermediate 11 was constructed via a sequence beginning from readily available ketone 5 and proceeding through bicyclo[3.2.1]ketone 8 by regioselective ring expansion.

, p. 59 - 63 (2007/10/03)
A total synthesis of (±)-patriscabrol (1) and (±)-boschnialactone (2) is described. The cyclopentapyranone skeleton is assembled by means of Baeyer-Villiger oxidation of ketol 5.
