Abstract

Abstract Monosubstituted alkanes as stereoisomers have been counted combinatorially by regarding them as nested planted promolecules, where the resulting numbers have been itemized with respect to carbon content (k), to the number of asymmetric carbons (l), as well as to the number of pseudoasymmetric carbons (m). To accomplish such itemization, the definitions of RS-stereogenic centers, asymmetric centers, and pseudoasymmetric centers have been discussed in detail. Each itemized number has been obtained as the coefficient of the term xkylzm appearing in a respective generating function, which has been derived by following Fujita’s proligand method (S. Fujita, Theor. Chem. Acc.2005, 113, 73; 2005, 113, 80; S. Fujita, Theor. Chem. Acc.2006, 115, 37). The itemized values up to carbon content 30 have been listed in tabular forms, which are distinctively concerned with achiral stereoisomers, chiral stereoisomers, and constitutional isomers (graphs).
