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 : Zup 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.
基于山梨酸的C 5单元在天然产物中普遍存在。为了补充生物合成算法,通过选择性能量转移催化( E : Z高达 99:1)实现了 β-硼基取代二烯的区域和立体选择性异构化。还公开了该方法在立体特异性[4+2]和[2+2]环加成过程中的应用,以生成具有四个连续立体中心的环状产物。
