In the past three decades, the heterocyclic oxazine cores have been intensely concerned.
Oxazine derivatives are promising vital heterocyclic motifs. They are eminent for their …

Presented herein is an atom-and step-economical method enabling the precise assembly of
a heptacyclic scaffold containing both azocine and indoline units through the cascade …

Many natural products and biologically important complex organic scaffolds have
convoluted structures around their core skeleton. Interestingly, with just changing the …

Piperidine scaffolds are present in a wide range of bioactive natural products and are
therefore considered as highly valuable, privileged synthetic targets. In this manuscript, we …

The AuI‐catalyzed reaction of 2‐(1‐alkynyl)‐2‐alken‐1‐ones with azomethine imines regio‐
and diastereoselectively affords furo [3, 4‐d] tetrahydropyridazines in a tandem cyclization …

A general and practical strategy for the construction of various keto-substituted
isoxazolidines via one-pot three-component reaction of easily accessible, safer and more …

Herein, we disclose the first report on the generation of cyanonitrone in situ from
diazoacetonitrile and nitrosoarene, and its subsequent [3+ 2] cycloaddition with oxabicyclic …

Hydrazones have been employed as the starting materials in a KOH-mediated one-pot three-
component cycloaddition with readily accessible nitroso compounds and olefins to construct …

A Brønsted acid-mediated synthesis of pyrazoles from conjugated hydrazones through a β-
protonation/nucleophilic addition/cyclization/aromatization sequence was developed. This …

This study describes an efficient approach to access oxime ethers via P (III)-mediated O–H
bond insertion reaction of oximes with α-keto esters. The strategy involves the protonation of …
