Catalyst-controlled regio- and stereoselective synthesis of diverse 12H-6,12-methanodibenzo[d,g][1,3]dioxocines.
We describe an efficient one-pot regio- and stereoselective method for synthesizing diverse 1-hydroxy-12H-6,12-methanodibenzo[d,g][1,3]dioxocines and 3-hydroxy-12H-6,12-methanodibenzo[d,g][1,3]dioxocines using ethylenediammonium diacetate (EDDA) or p-toluenesulfonic acid (PTSA) catalyzed reactions between various resorcinols and a number of 2-hydroxychalcones. These reactions involve a catalyst...
متن کاملCatalyst-controlled stereoselective olefin metathesis as a principal strategy in multistep synthesis design: a concise route to (+)-neopeltolide.
Molybdenum-, tungsten-, and ruthenium-based complexes that control the stereochemical outcome of olefin metathesis reactions have been recently introduced. However, the complementary nature of these systems through their combined use in multistep complex molecule synthesis has not been illustrated. A concise diastereo- and enantioselective route that furnishes the anti-proliferative natural pro...

Stereoselective synthesis of (-)-spicigerolide.
(-)-Spicigerolide was stereoselectively synthesized from a protected (S)-lactaldehyde. The synthesis of the polyacetylated framework relied on two Zn-mediated stereoselective additions of alkynes to aldehydes as well as a regiocontrolled [3,3]-sigmatropic rearrangement of an allylic acetate. The pyranone moiety was constructed via ring-closing metathesis.
