Cycloisomerization of 1,6-Enynes: Asymmetric Multistep Preparation of a
Framework in Water with Polymeric Catalysts. — The title reaction is
20- 092 Hydrindan
investigated for a variety of substrates catalyzed by the polymer-supported palladium
complex (I) in water. The corresponding products are obtained in excellent yields. A
tandem cyclization/Diels—Alder reaction is described for the preparation of triester
(XIII). Furthermore, the methodology is applied to the synthesis of enantiopure (VIIc)
in three steps using the polymer-supported catalysts (XIV), (XV) and (I). — (NAKAI,
