Although its intriguing features, such as uniform functionalization through the entire beads and a very high-loading capacity are suitable candidates for solid-phase synthesis and reagent-scavenging, the use of Rasta resin as support for organocatalysis has been little explored. In this contribution, Rasta polymer has been used to preparation of high-loading Rasta-TBD. This catalyst has been able to efficiently promote several organic transformations with constantly good and promising results. (C) 2011 Elsevier Inc. All rights reserved.
Deacetylative Amination of Acetyl Arenes and Alkanes with C–C Bond Cleavage
The Brønsted acid-catalyzedsynthesis of primary amines from acetyl arenes and alkanes with C–C bond cleavage is described. Although the conversion from an acetyl group to amine has traditionally required multiple steps, the method described herein, which uses an oxime reagent as an amino group source, achieves the transformation directly via domino transoximation/Beckmann rearrangement/Pinner reaction
