This study describes a microfluidic thread-based analytical device (μTAD) capable of in situ mass spectrometric analysis for continuous flow reaction monitoring. Organic reaction screening is foundational to drug discovery. Microfluidic devices are of special interest here because they provide continuous reaction monitoring with advantages such as the use of smaller reagent volumes and short analysis times.

This study investigates the repurposing of asphaltene, a petroleum waste product, as a catalyst for organic reactions. Sulfonated asphaltene was synthesized and evaluated for its efficacy in catalyzing the Mannich reaction, displaying notable diastereoselectivity and operating effectively under mild conditions. Characterization of the catalyst's chemical composition, structure, and thermal stability was conducted using FT-IR, TGA, XRD, CHN, BET-BJH, SEM, and EDS analyses.

Bifunctional thiourea-based organocatalysts facilitate an enantioselective desymmetrization and Lossen rearrangement cascade reaction of -sulfoxy -succinimides, resulting in the synthesis of cyclic β-amino acid derivatives. This catalytic system was optimized for bicyclic and tricyclic succinimide substrates affording yields from 61-91% and up to 96:4 er. This reaction proceeds via the group selective addition of the primary alcohol nucleophile to an enantiotopic carbonyl group with sequential rearrangement of the intermediate -sulfonyl hydroxamate ester.

Cyclic -sulfonyl aldimines are well-known aza-[2]-synthons for various [2 + ] annulation reactions. Herein we describe a novel base mediated [2 + 1] annulation and a regioselective aziridine ring-opening reaction cascade, which provides an efficient and distinct synthetic strategy from readily available cyclic -sulfonyl aldimines and -carbonyl sulfonium salts leading to -amino ketone derivatives through the corresponding fused tri-substituted aziridines. This one-pot, two-step process involves formation of C-C and C-N bonds and subsequent cleavage of a C-N bond.
