Abstract

Abstract A tandem gold-catalyzed cycloisomerization/Suzuki cross-coupling sequence involving arylethynyl-N-methyliminodiacetic acid boronates is described. Combining the mildness of homogeneous gold catalysis with the versatility of N-methyliminodiacetic acid (MIDA) boronates, this tandem two-step method enables the rapid assembly of various aryl- substituted heterocycles without having to isolate or purify any heterocyclic MIDA boronate ...
