to classical hydroboration and boron-Wittig reactions,
a new, efficient access to cyclic 1,3-dienyl boronic esters has been
developed via diene or triene metathesis. Subsequently,
fused pyrroles were synthesized with a broad substrate scope from
the reaction of cyclic 1,3-dienyl boronic esters with arylnitroso
compounds using a one-pot hetero-Diels–Alder/ring contraction
sequence.
