Heterogeneously Catalyzed Cascade Oxidative Coupling/Dearomative Spirocyclization of Diarylamines: Facile Access to Spiroacridines

Advanced Synthesis &Catalysis, EarlyView.
Abstract Spirocyclic compounds, particularly spirocyclohexadienones, are important in pharmaceuticals due to their biological activity. In this study, we develop a catalytic cascade oxidative spirocyclization of diarylamines for the rapid access to highly functionalized spirocyclohexadienones. Using commercially available recyclable heterogeneous metal

Asymmetric synthesis of highly substituted spiro[2H‐pyrrole‐2,3‐succinimide] derivatives by copper‐catalyzed post‐Ugi reactions

Advanced Synthesis &Catalysis, Accepted Article.
Herein we present a novel one‐por methodology for the synthesis of enantioenriched 2H‐pyrrolespirosuccinimides by copper‐catalyzed reactions on Ugi adducts derived from enantiopure α‐alkylbenzyl amines through a chirality transfer process. We have proposed a mechanism supported by density functional theory (DFT) calculations, where a hydrogen radical ...

Development of Photo‐Biocatalytic Redox System for Asymmetric Synthesis of Optically Active Amines Using Blue Light and Transaminases. A Case Study Toward Mavacamten

Advanced Synthesis &Catalysis, EarlyView.
Abstract α‐Chiral amines are versatile building blocks for the asymmetric synthesis of optically pure high‐added‐value chemicals, including pharmaceuticals, agrochemicals, and natural products. Herein, we report a one‐pot, two‐step sequential deracemization of racemic sec‐alcohols to optically enriched primary amines throught a photo‐biocatalytic ...

Modular Synthesis of 2,3,4,6‐Tetrasubstituted Thieno[2,3‐c]furans Based on Formal [3+2] Cycloaddition Utilizing [1,2]‐Phospha‐Brook Rearrangement / Brønsted Base‐Mediated Cyclization Strategy

Advanced Synthesis &Catalysis, EarlyView.
Abstract A modular synthesis of 2,3,4,6‐tetrasubstituted thieno[2,3‐c]furans, which employs a formal [3+2] cycloaddition utilizing the [1,2]‐phospha‐Brook rearrangement and a subsequent Brønsted base‐mediated cyclization, has been established, providing an efficient access to a wide range of densely functionalized thieno[2,3‐c]furans that are otherwise

Impact of edaphoclimatic conditions and crop season on olive oil's fatty acids

Agronomy Journal, Volume 114, Issue 6, Page 3118-3128, November/December 2022., 2022
Abstract The olive tree (Olea europaea L.) fruit oil attracts widespread interest because of its high content of monounsaturated fatty acids. However, a neglected area in the field is the edaphoclimatic factors impact, which is poorly understood. Bearing this in mind, the purpose of this investigation was to evaluate the impact of the edaphoclimatic ...
