摘要
(Figure Presented) A crystal from the China sea: The asymmetric total synthesis of (+)-vigulariol (see picture: red O, blue C, white H) has been accomplished in eight linear steps starting from (R)-cryptone, which is readily available from eucalyptus oil. Key steps involve an asymmetric homoaldol reaction of chiral allyl carbamates and THF cyclocondensation. Ring-closing metathesis led to the tricyclic framework of the cladiellin diterpenes. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
