Synthesis of Sulfur Heterocycles by Palladium‐Catalyzed Cyclization
European Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.In spite of the well‐known palladium thiophilicity, sulfur‐containing acyclic substrates may efficiently undergo several different kinds of palladium‐catalyzed cyclization processes leading to highly important sulfur heterocycles in one synthetic step. Advances in this challenging and stimulating field of research are presented in this review.

Advanced Synthesis &Catalysis, Volume 368, Issue 7, 1 April 2026.A dioxolanyl linchpin has been used to synthesize aryl ethanolamines from readily available aryl bromide and amine starting materials using a metallaphotoredox/substitution telescoped sequence. This combinatorial approach allows for a wide synthetic scope of both heteroarenes and cyclic amines. Aryl ethanolamines are an important functional group found

Asian Journal of Organic Chemistry, Volume 15, Issue 4, April 2026.Access to pyrazoles arylated at C4 and C5 positions remains challenging due to their similar reactivity under Pd‐catalyzed C–H activation conditions. Herein, we report on the synthesis of 4‐aryl‐5‐heteroarylpyrazoles involving Suzuki‐coupling, followed by Pd‐catalyzed C–H heteroarylation.
