Abstract
The Sc(III)-catalyzed [2,3]-sigmatropic rearrangement of sulfonium ylides derived from azoalkenes has been established. Owing to the absence of a carbenoid intermediate, this protocol represents the first non-carbenoid variant of the Doyle-Kirmse reaction. Under mild conditions, a variety of tertiary thioethers have been readily prepared in good to excellent yields.

Abstract
![]()
An unprecedented
synthesis of polysubstituted indole-fused pyridazines
(azacarbolines) from α-indolylhydrazones under oxidative conditions
using a combination of iodylbenzene (PhIO2) and trifluoroacetic
acid (TFA) has been developed. This transformation is conducted without
the need for transition metals, harsh conditions, or an inert atmosphere.

Abstract

Zn(II)-catalyzed
divergent synthesis of functionalized polycyclic
indolines through formal [3 + 2] and [4 + 2] cycloadditions of indoles
with 1,2-diaza-1,3-dienes (DDs) is reported. The nature and type of
substituents of substrates are found to act as a chemical switch to
trigger two distinct reaction pathways and to obtain two different
types of products upon the influence of the same catalyst. The mechanism
of both [4 + 2] and [3 + 2] cycloadditions was investigated and fully
rationalized by density functional theory (DFT) calculations.

Abstract
Chiral phosphoric acid-catalyzed highly enantioselective formal [3 + 2] cycloaddition reaction of azoalkenes with 3-vinylindoles has been established. Under mild conditions, the projected cycloaddition proceeded smoothly, affording a variety of 2,3-dihydropyrroles in high yields and excellent enantioselectivities, and also in a diastereospecific manner. As opposed to the common 4-atom synthons in the previous literature reports, azoalkenes served as 3-atom synthons. Besides, the observed selectivity was supported by primary theoretical calculation. The unique chemistry of azoalkenes disclosed herein will empower asymmetric synthesis of nitrogen-containing ring structural motifs in a broader context. Chiral phosphoric acid catalyzed formal [3 + 2] cycloaddition reaction 2,3-Dihydropyrroles were enantioselectively synthesized Azoalkenes served as 3-atom synthons

Abstract
The enantioselective dearomatization of indoles by an organocatalytic (3+2) reaction has been established. The reaction makes use of simple indole derivatives as substrates, and employs azoalkenes reaction partners. A wide range of pyrroloindolines containing an all-carbon quaternary stereogenic center were readily prepared in high yields and with excellent enantioselectivities.

Abstract
Substituted hydroxy-benzofurans are easily accessible by treatment of resorcinols and 1,2-diaza-1,3-dienes (DDs) under acidic conditions. The reaction happens through an uncommon Michael reaction between aromatic derivatives as aromatic C(sp2)-H nucleophiles and DDs as acceptors. Also, the behavior of different phenols and 2-naphthol was investigated.
