Br?nsted Acid Promoted Thermal-Ring-Rearrangement of Fluorenopyrans to 2-(1H-Inden-3-yl)-9H-fluoren-3-ols Bearing Two All-Carbon-Quaternary Centres

4-Aryl-fluorenopyrans bearing quaternary centre at C2 and C6 positions underwent a thermal-ring-rearrangement with a catalytic amount of pTsOH to furnish 2-(1H-inden-3-yl)-9H-fluoren-3-ols with two all carbon-quaternary centres, in which one is retained a

Calcium-Catalyzed Intramolecular Hydroamination-Deacylation Reaction of in situ formed β-Amino Allenes

We have developed a simple, One-Pot, three-component reaction of tert-propargyl alcohols, primary amines and acyl ketones to synthesize fully substituted pyrroles and pyridine derivatives in good to excellent yields with large substrate diversity. An eco-friendly calcium catalyst catalyzes the reaction to form the key intermediate β-amino allene that undergoes subsequent Thorpe-Ingold effect assisted hydroamination and aromaticity driven deacylation reaction to yield fully substituted five and six-membered azacyclic compounds. (Figure presented.).

In Situ Generation of Allenes and their Application to One-Pot Assembly of Functionalized Fluoreno[3,2-b]furans by Calcium-Catalyzed, Regioselective, 3-Component Reactions

We have developed a novel synthetic methodology for the preparation of tetra-annulated fluorenofurans and fluorenopyrans using calcium(II)-catalyzed one-pot, three-component reaction. In this reaction, tert-propargyl alcohols react with 1,3-dicarbonyls to form tetra-substituted allenes, which are subsequently undergoing regiodivergent annulation with sec-propargyl alcohols to produce the fluorene-fused furan compounds. Broad substrate scope, regioselectivity, gram-scale synthesis, and benzylic functionalization of products are some of the highlights of this protocol.
