Topicity and Stereogenicity,d many reviews for clarifying or getting rid of such ambiguity.. The term . was originally proposed by McCasland. in order to avoid confusions provided by so-called “asymmetric” and “pseudoasymmetric” carbon atoms. The term stereogenic has been utilized as a key concept in the revised CIP-system for

Counting Orbits,is of fundamental importance, not only because of its wide applicability but also because of its conceptual depth.. Many mathematical textbooks have dealt with the topics in various manners.. Chemical enumerations have been reviewed in several books. and articles.. Recent advances of chemical enumer

Cage-Shaped Molecules with High Symmetries,tial interesting properties.. Two strategies have been applied to the derivation of new compounds of given symmetries. The first is a vertex strategy in which substituents are placed on vertices of a parent skeleton..The second (edge strategy) consists of the insertion of methylene or other units in

Elementary Superposition,established by Redfield,. rediscovered independently by Read. and later refocussed by several mathematicians.. Lloyd. has actually applied this theorem to chemical enumerations. All of these methods are capable of enumerating chemical objects with respect only to their weights (molecular formulas).

Compounds with Achiral Ligands Only,od that is a combination of table of marks and double cosets. These methods, however, have taken no account of intransitivity of a domain explicitly; hence, they have disregarded the restriction due to OMVs (obligatory minimum valencies).
