Abstract
A novel approach for the synthesis of carbene adducts 9a/9b and 10/11 is reported. Identification of the geometric and positional isomers of carbene addition was carried out by reversed‐phase HPLC, and the establishment of the structure and configuration of 9a/9b was performed by means of 2D‐NMR.
