Use of chelation control to direct the stereochemical outcome of intramolecular additions of allylsilanes to β-dicarbonyl substrates is described.Excellent diastereoselectivity is achieved by titanium tetrachloride promoted cyclization of a wide variety o
CHELATION-CONTROLLED CYCLIZATION OF β-KETOESTER-SUBSTITUTED AND β-KETOAMIDE-SUBSTITUTED ALLYLSILANES.
Molander, Gary A.,Andrews, Steven W.
, p. 3115 - 3118 (2007/10/02)
The first examples of Lewis acid-catalyzed chelation-controlled cyclization reactions are reported.Titanium tetrachloride-initiated cyclization of β-ketoester and β-ketoamide-substituted allylsilanes proceeds in isolated yields of 65-88percent, providing
