DOI: 10.1016/j.tet.2017.10.049

Abstract: Abstract Oxindole derivatives are of growing importance in organic synthesis and in the synthesis of biologically active compounds, therefore, a very important goal is to develop new ways of modifying such scaffold. In this article… read more here.

DOI: 10.1039/d3qo00412k

Abstract: Herein, we design and develop a one-pot cascade strategy for the assembly of multi-substituted conjugate oxindole derivatives. This approach represents a new reaction mode for carbene gem-difunctionalization by delayed acyl transfer instead of delayed proton… read more here.

DOI: 10.4014/jmb.2110.10039

Abstract: A chemical investigation of a culture extract from Streptomyces sp. RK85-270 led to the isolation and characterization of two new oxindoles, RK-270D (1) and E (2). The structure of 1 and 2 were determined by… read more here.
