The present invention relates to a method for preparing a macromolecular composition comprising indene-derivatives. The invention also relates to the macromolecular compositions per se, and to methods of using the macromolecular compositions. The macromolecular compositions are useful for undergoing subsequent reactions with small molecules.
hyl)-1,3-butadiene, have been synthesized and their diene-transmissive Diels-Alder cycloadditions are investigated. The initial Diels-Alder reaction selectively occurs not across the diene part substituted with the alkoxyl moiety but the monosubstituted diene. Some cross types of diene-transmissive Diels-Alder reaction are demonstrated using the triene equivalent and two different dienophiles.
Substituierte Olefine werden aus Aryldiazoniumsalzen und Olefinen in Gegenwart eines Palladiumkatalysators und gegebenenfalls in Gegenwart einer Base hergestellt.
取代烯烃是在钯催化剂存在下,必要时在碱存在下,由芳基重氮盐和烯烃制得的。

Bicylolactones from Diels-Alder (D A) cycloadditions of 3,5-dibromo-2-pyrone can undergo various palladium catalyzed cross Coupling reactions to afford a series of alkenyl, alkynyl and aryl bicyclolactones. The resulting coupled products can be readily converted into various 3-OH cyclohexenes via lactone ring openings, while those bearing dienyl units underwent highly diastereoselective D-A cycloadditions with selected dienophiles to furnish multiply functionalized polycarbocycles.
