Abstract: The Rh(III)-catalyzed dual directing group assisted C-H activation/annulation of 3-arylisoxazolones with propargyl alcohols has been developed, which expands the application scope of isoxazolones in organic synthesis. This protocol also worked well with 3-aryl-1,4,2-dioxazol-5-ones to produce… read more here.

DOI: 10.1021/acs.orglett.2c01011
Abstract: A straightforward synthesis of pyrimidines via Au(III) or Au(I)/Lewis-acid-catalyzed cascade reactions of propargyl alcohols with 3-amino-benzo[d]isoxazoles is described. The propargyl amine intermediates are readily generated in situ via oxophilic activation of gold(III) or a Lewis… read more here.

DOI: 10.1039/d2ra03540e
Abstract: The Meyer–Schuster rearrangement of propargyl alcohols or alkynols leading to α,β-unsaturated carbonyl compounds is well known. Yet, electrophilic halogenations of the same alkynols and their alkoxy, ester and halo derivatives are inconspicuous. This review on… read more here.

DOI: 10.1055/s-0036-1591735
Abstract: Multiple bond-forming cascade transformations and one-pot procedures are valuable tools in organic synthesis and drug discovery. These atom-economical processes provide rapid access to natural product-like scaffolds from simple precursors. Herein, we report on ruthenium-catalyzed one-pot… read more here.
