Reference Reading

1. Studies directed toward the synthesis of terreulactone A: rapid construction of the A, B, C rings
Haibo Liu, Dionicio R Siegel, Samuel J Danishefsky Org Lett. 2006 Feb 2;8(3):423-5. doi: 10.1021/ol052618p.
[structure: see text]. An efficient, rapid synthesis of the A, B, C rings of terreulactone A is described. Key steps in the synthesis include a diastereoselective benzylic acid rearrangement to create the desired quaternary center at C2 and a mild bromolactonization to assemble the lactonic ring A.
