Highly Regioselective Synthesis of Indene Derivatives Including an Allene Functional Group via Pd/C-Catalyzed Cyclization Reaction in Air
摘要:
Indene derivatives including an allene functional group are readily prepared in moderate to excellent yields with high regioselectivity under very mild reaction conditions by the Pd/C-catalyzed reaction of propargylic compounds. The resulting products can be further elaborated using Pd-catalyzed annulation reactions.
New light on an old reaction: phase-transfer-catalyzed intramolecular cyclization of propargyl compounds for synthesis of indene derivatives and disubstituted benzo[b]furans
A variety of indene derivatives and disubstituted benzo[b]furans are readily prepared under the mild reaction condition from propargylic compounds by phase-transfer catalysis (PTC) instead of metal catalysis.
在温和的反应条件下,通过相转移催化(PTC)代替金属催化,由炔丙基化合物可轻松制得各种茚衍生物和二取代的苯并[ b ]呋喃。
Highly Regioselective Synthesis of Spirocyclic Compounds by a Palladium-Catalyzed Intermolecular Tandem Reaction
We have disclosed a very nice advance of nickel(II)-catalyzed carboannulation reactions. Highly substituted indene derivatives are readily prepared in moderate to excellent yields under very mild reaction conditions in air via a nickel (II)-catalyzed cyclization of propargylic compounds with soft nucleophiles.
