Asymmetric Synthesis of Highly Substituted Spiro[2H‐pyrrole‐2,3‐Succinimide] Derivatives by Copper‐Catalyzed Post‐Ugi Reactions

Advanced Synthesis &Catalysis, EarlyView.
Abstract Herein we present a novel one‐pot 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

Dual Photoredox/Cu‐Catalysis Enables Diastereoselective Synthesis of 3‐β‐Ethynyltropanes via Decarboxylative Alkynylation

Advanced Synthesis &Catalysis, EarlyView.
A copper‐catalyzed decarboxylative alkynylation of tropanes is developed. This approach works under mild conditions and selectively produces a range of 3‐β‐alkynylated tropanes. Moreover, it provides a versatile and convergent platform for further functionalization of the triple bond.

para-Selective C-H amidation of simple arenes with nitriles [PDF]

, 2015
A para-selective C-H amidation of simple arenes with nitriles has been developed. By increasing the amount of arenes, a further meta-selective C-H arylation of the produced amides occurred.

Microwave‐Assisted One‐Pot Synthesis of Alkyl Levulinates From Post‐Harvest Vegetable Waste

Advanced Sustainable Systems, EarlyView.
Vegetable waste is valorized through Soxhlet extraction using H₂O₂ and heteropolyacid (HPA), followed by material characterization (XRD, FTIR, TGA, DSC). A microwave‐assisted reaction at 170 °C for 30 min with HPA and alcohol yields bio‐based esters.
