Stereoselective Synthesis and Structural Correction of the Naturally Occurring Lactone Stagonolide G César A. Angulo-Pachón Santiago Díaz-Oltra Juan Murga Miguel Carda J. Alberto Marco 10.1021/ol102599e.s002 https://acs.figshare.com/articles/journal_contribution/Stereoselective_Synthesis_and_Structural_Correction_of_the_Naturally_Occurring_Lactone_Stagonolide_G/2704228 A convergent synthesis of the structure proposed for the naturally occurring lactone stagonolide G is described. All three stereocenters were created with the aid of asymmetric Brown allylations. The lactone ring was built by means of a ring-closing metathesis (RCM). The synthetic and the natural compound differed in their spectral properties. A new structure is now proposed for stagonolide G and demonstrated by means of a chemical transformation. 2010-12-17 00:00:00 stereocenter metathesi RCM Stereoselective Synthesis Brown allylations lactone stagonolide G Structural Correction chemical transformation lactone ring compound Occurring Lactone Stagonolide G stagonolide G aid convergent synthesis
