密度泛函理论计算表明,TAN-1085合成前体中的芳香取代基和双甲氧基取代基效应强烈地有利于[1,7] σ迁移氢位移,而6 π电环化途径则不利于合成。
DFT calculations show that aromatic and bis-methoxy substituent effects in a synthetic precursor of TAN-1085 strongly favor a [1,7] sigmatropic hydrogen shift over the 6pi electrocyclic pathway, rendering the latter unfavorable in synthesis.
