Oxygen‐bearing motifs, mainly the congener heterocycles are ubiquitous due to their
presence in various natural products and bioactive scaffolds. Although in literature, several …

The construction of carbon-carbon bond through the metathesis reactions between
carbonyls and olefins or alkynes has attracted significant interest in organic chemistry due to …

A metal-free Lewis acid-initiated protocol for the synthesis of highly substituted 3-
(dihydrofuran-3 (2 H)-ylidene) isobenzofuran-1 (3 H)-imines from 2-(4-hydroxybut-1-yn-1-yl) …

Two tunable cascade reactions of alkynols and alkynes have been developed by combining
Sc (OTf) 3 and rhodium catalysis. In the absence of H2O, an endo‐cycloisomerization/C H …

Skeletal reorganization reactions have emerged as an intriguing tool for converting readily
available compounds into complicated molecules inaccessible by traditional methods …

As the first cascade C–H activation directed by a transient group, reaction of alkynols and 7-
oxabenzonorbornadienes has been achieved via synergistic rhodium and scandium …

This article is a comprehensive report describing our studies in the field of aza-alkynyl Prins
chemistry, comparing and contrasting the different reaction partners and reactivities …

This review focuses on alkynyl Prins and alkynyl aza-Prins cyclization processes, which
involve intramolecular coupling of an alkyne with either an oxocarbenium or iminium …

Lewis acid mediated multisegment coupling cascade is designed for the synthesis of
densely substituted 4-alkoxy quinolines via an oxonium ion triggered alkyne carboamination …

An efficient one‐pot method for the enzyme‐and ruthenium‐catalyzed enantioselective
transformation of α‐allenic alcohols into 2, 3‐dihydrofurans has been developed. The …
