intermolecular coupling of unactivated alkenes, including isomerizable alkenes, to a range of heterocycles using a Rh(I) catalyst. A variety of functional groups were incorporated, including esters, nitriles, and acetals. The intermolecular coupling became possible after it was discovered that weak acids dramatically increase the rate of both the inter- and intramolecularreactions.

A new method for the preparation of 2-substituted oxazolines by rhodium-catalyzed coupling of alkenes with 4,4-dimethyl-2-oxazoline is reported. The oxazoline products are obtained in good yield with excellent selectivity for the linear product. A variety of alkene substitution patterns and functional groups are tolerated. This procedure represents an attractive alternative to hydroesterification because

日期:——
The Z-selective cross metathesis of allylic-substituted olefins is explored with recently developed ruthenium-based metathesis catalysts. The reaction proceeds with excellent stereoselectivity for the Z-isomer (typically >95%) and yields of up to 88% for a variety of allylicsubstituents. This includes the first synthesis of Z-alpha,beta-unsaturated acetals by cross metathesis and their elaboration
