Highly substituted benzannulated cyclooctanol derivatives by samarium diiodide-induced cyclizations
Beilstein Journal of Organic Chemistry, 2010 A series of γ-oxo esters suitably substituted with various styrene subunits was subjected to samarium diiodide-induced 8-endo-trig cyclizations. Efficacy, regioselectivity and stereoselectivity of these reactions via samarium ketyls strongly depend on ...

Naturally occurring long-chain β-hydroxyketones
Journal of Lipid Research, 1971 A fraction comprising about 0.7% of the extractable surface lipids of cabbage (Brassica oleracea) leaves was isolated and identified as a mixture of isomeric βhydroxyketones consisting mainly of 14-keto-16-hydroxynonacosane and 15-keto-13 ...
