Highest priority on a chiral centre
Web5.3 Designating R vs. S Configuration / Four Steps • “R” or “S” is assigned to a chiral center using a stepwise procedure 1. Using atomic numbers, prioritize the four groups attached to the chiral center (1, 2, 3 and 4) 2. Arrange the molecule in space so the lowest priority group faces away from you 3. Web6 A. Kasal atoms. Thus, C-24 carbon is treated differently in ergosterol and dihydroergosterol (see Fig. 1.8a). Having assigned priority to individual substituents at each centre, we turn to the

WebRule 2. If there are two substituents with equal rank, proceed along the two substituent chains until there is a point of difference. First, determine which of the chains has the first … WebOne of the most interesting types of isomer is mirror-image stereoisomers, a non-superimposable set of two molecules that are mirror images of one another. The existence of these molecules is determined by concept known as chirality. The word “chiral” was derived from the Greek word for hand, because our hands are good example of chirality ...

Yes, here Nitrogen has to be considered as a stereocenter. Also, you can assign R and S to it. The rule is that the lone pair has the least priority and then you can assign R and S as you do for other molecules. In terms of CIP-rules, I agree.
