units are ubiquitous in natural products. To complement biosynthesis algorithms, a regio- and stereo-selective isomerization of β-boryl-substituted dienes has been achieved by selective energy transfer catalysis (E : Z up to 99 : 1). Application of the method in stereospecific [4+2] and [2+2] cycloaddition processes is also disclosed to generate cyclic products with four contiguous stereocenters.
