title: Stereodivergent total syntheses of precoccinelline, hippodamine, coccinelline, and convergine.
abstract: [structure: see text] A stereodivergent approach toward total syntheses of Coccinellidae defensive alkaloids is described. These syntheses feature a highly diastereoselective intramolecular aza-[3 + 3] annulation strategy, which represents a de novo approach to this family of natural products.
