title: The first enantioselective total synthesis of the anti-Helicobacter pylori agent (+)-spirolaxine methyl ether.
abstract: The first enantioselective synthesis of the anti-Helicobacter pylori agent (+)-spirolaxine methyl ether has been carried out in a convergent fashion by heterocycle-activated Julia olefination of a spiroacetal-containing sulfone fragment with a phthalide-containing aldehyde fragment. The total synthesis of (+)-spirolaxine methyl ether establishes the absolute stereochemistry of the natural product to be (3R,2''R,5''R,7''R).
