Let us quantify the LEF of the complex (solvated PB1+ HM1) along the reaction axis (Z -direction) and the lateral direction (Y-axis). Such a 2dimensional (2D) electric field was demonstrated in the past to bring about reactivity enhancement as well as enantioselectivity. Thus, we expect that the LEF along the Z-axis affects reactivity while along the Y-axis, it affects the enantioselectivity. Our analysis in Figure While oxidant HM1 is known to be intrinsically reactive in H-atom-transfer (HAT) reactions , the enantioselectivity has not been explored. As can be seen from Figure which represents a snapshot from 100 ns MD simulation, the substrate occupies a very a close position to the oxidant, and both pro-R and pro-S hydrogen atoms are also in the proximity of the oxo-iron moiety of HM1. The proximities of these hydrogen atoms are also persistent throughout the simulations which can be verified by the distance vs. time plot (Figure ) and the plot of distance vs population (Figure ). At the same time, it is apparent that the pro-R hydrogen is closer than the pro-S one. As mentioned earlier, hydroxylation of tetralin at pro-R position has medicinal importance . It is noteworthy that our modeled system gives a clear preference for pro-R selectivity, and is thus of industrial relevance.
