Using the strain inherent in a cyclobutyl ring to counteract the stabilization of a radical adjacent to a boronic ester allows the synthesis a broad variety of 1,2- and 1,3-disubstituted cyclobutylboronic esters.

The development of a series of novel 7-azabenzofurans exhibiting pan-genotype inhibition of HCVNS5Bpolymerase via binding to the primer grip site is presented. Many challenges, including poor oral bioavailability, high clearance, bioactivation, high human serum shift, and metabolic stability were encountered and overcome through SAR studies. This work culminated in the selection of BMS-986139 (43)

motif. This new reaction was harnessed to achieve the first completely stereocontrolled total synthesis of (-)-peridinin. This synthesis was accomplished using only one reaction iteratively to assemble four fully functionalized building blocks with complete stereoretention at each initial halide or boron-bearing carbon. This synthesis elevates the capacity of the iterative cross-coupling strategy to an
