DOI: 10.1016/j.tet.2018.05.001

Abstract: Abstract The reactivity of indole based bis-propargyl ethers 4a-4g under Garratt-Braverman condition (KOBut in refluxing toluene) has been studied. Interestingly, these propargyl systems with one arm attached with substituted 3-indolyl derivatives leaving the other arm… read more here.

DOI: 10.1021/acs.orglett.1c01256

Abstract: The first Cu-catalyzed dehydrogenative C-O cyclization for the synthesis of furan-fused thienoacenes is described. A variety of heteroacenes including a thieno[3,2-b]furan or a thieno[2,3-b]furan skeleton were synthesized by intramolecular C-H/O-H coupling. The use of a… read more here.

DOI: 10.1038/s41467-024-49664-5

Abstract: Cycloaddition reactions play a pivotal role in synthetic chemistry for the direct assembly of cyclic architectures. However, hurdles remain for extending the C4 synthon to construct diverse heterocycles via programmable [4+n]-cycloaddition. Here we report an… read more here.

DOI: 10.1039/c7cc00218a

Abstract: A gold-catalyzed ring-expansion reaction of alkynones to access furan-fused polycyclic compounds is reported. Mechanistic studies revealed that the reaction might occur through a tandem 1,2-acyl migration/Friedel-Crafts reaction. read more here.
