A convenient and highly stereoselective method for synthesis of octahydropyrano[3,2-b]pyrrole derivatives

, 2013
The octahydropyrano[3,2-b]pyrrole derivatives are synthesized by a double reductive amination from pyranose derivatives of nono-2,5-diuloses and octos-4-uloses and various amines.

Sustainable Synthesis of 4,7‐Dihydro‐4,7‐ethano‐2H‐isoindoles—Key Building Blocks to Benzoporphyrins

Chemistry – A European Journal, EarlyView.
A facile and sustainable route to isoindole derivatives—key benzoporphyrin precursors—brings high‐ and low‐symmetry benzoporphyrins closer to practical application. ABSTRACT Benzoporphyrins, π extended porphyrin analogues, exhibit remarkable potential for optoelectronic and theragnostic applications, yet have remained largely confined to fundamental ...

Synthesis and Characterization of Nickel(II) Complex Containing 2-(t-Butylaminomethyl)pyrrole

, 2013
[[abstract]]Two aminopyrroles, 2-(t-butylaminomethyl)pyrrole (HL1) and 2,5-di(t-butylaminomethyl)pyrrole (HL2), were synthesized and the hydrogen-bond interactions were observed in the single-crystal X-ray structures of HL1 HCl and HL2.

Light‐Induced Anion Translocation to Control Helical Folding in an Artificial Communication System

Chemistry – A European Journal, EarlyView.
Anion‐induced helical folding of an oligomer is controlled indirectly and reversibly by light through anion uptake/release by a photoresponsive receptor. Thus, a light signal is processed into a chemical signal in a communication‐type three‐component supramolecular system.

Total Syntheses of Agelamadin F and (±)‐Tauroacidin A, Enabled by NaClO2‐Mediated Coupling Reactions of Oroidin and Amines

Chemistry – A European Journal, EarlyView.
Total syntheses of agelamadin F and (±)‐tauroacidin A were achieved by sodium chlorite (NaClO2)‐mediated oxidative C─N coupling. Nine C15–N–amino acid‐substituted oroidin derivatives were successfully prepared to demonstrate the applicability and versatility of this oxidative coupling reaction.

Strain Release of 1‐Azabicyclo[1.1.0]butanes as a Gateway to Highly Functionalized Azetidines: New Strategies and Structural Motifs

Chemistry – A European Journal, EarlyView.
Over the past decade, the interest in azetidines has continuously risen, by virtue of their highly appealing pharmaceutical properties. Monocyclic, spirocyclic, and bridged azetidines can be accessed by leveraging 1‐azabicyclo[1.1.0]butanes as precursors.
