The stereoselective total synthesis of (3R,5R)-sonnerlactone and (3R,5S)-sonnerlactone
摘要:
The stereoselective synthesis of (3R,5R)-sonnerlactone (1) and (3R,55)-sonnerlactone (2) has been accomplished starting from L-aspartic acid. Our strategy involves asymmetric allylation, Alder-Rickert reaction and Mitsunobu macrolactonization as the key steps. (C) 2012 Elsevier Ltd. All rights reserved.

A multiple equilibration strategy as a general approach to asymmetric synthesis has been demonstrated. The generation, multiple equilibration, and manipulation of methyl-substituted 4,10-diketo-1,7-dioxaspiro[5.5]-undecanes has led to the synthesis of polypropionate fragments containing tetrahydropyran rings containing seven contiguous stereocenters in only five steps with complete stereocontrol.

A Novel Route to the Vinyl Sulfide Nine-Membered Macrocycle Moiety of Griseoviridin<sup>†</sup>
The synthetic potentialities of cerium(III) chloride are demonstrated by the synthesis of a nine-membered ring heterocycle component of Griseoviridin (3) in optically active form. The key step involves the stereospecific formation of the alpha-carbalkoxy alkenyl sulfide moiety using a combination system of cerium(III) chloride heptahydrate and sodium iodide.
