Canterbury, Daniel P.,Micalizio, Glenn C.

, p. 2384 - 2387 (2011/06/26)

Chemical equations presented. A convergent synthesis of the CDEF-tetracyclic region of pectenotoxin-2 (PTX-2) is described. The synthetic pathway derives from a head-to-tail union of 2 equiv of linalool to establish a stereodefined DEF-tricyclic aldehyde.
