A high-yield synthesis of [1-15 N]-2Π-deoxyinosine ( 5), [4-counterpart, through [1-15 N]-2Π-deoxyinosine (5), and successively, [4-15 N]-2Π-deoxyAICAR ( 7). [1-15 N]-2Π-15 N]-2Π-deoxyAICAR (7), and [1-15 N]-2Π-deoxyguanosine (10) from 2Π-deoxyinosine (1) using relatively low expensive Deoxyguanosi
## Abstract The synthesis of ^15^Nβlabelled nornicotine **2** and ^15^Nβlabelled nicotine **1** is described via the reductive aminocyclization of a 1,4βketoaldehyde with a corresponding amine in the presence of sodium cyanoborohydride. Yields of 30% and 26%, respectively, were obtained from 3βbrom
