Abstract
[14‐^14^C]‐allo‐berbane‐14‐ol: (7,8‐methylenedioxy‐14α‐hydroxy‐[14‐^14^C]‐allo‐berbane, [14‐^14^C]1 spec, act.: 405 MBq/mM) was synthesized in nine reaction steps from K^14^CN (overall radioactive yield: 2.8%).

Conditions were found for almost quantitative carboxylation of n-hexyllithium with l4CO2 to afford lithium [1-l4C] heptanoate. It was then possible to perform the reaction sequence lithium [1-l4C] heptanoate --+ [l-14C] heptan-1-01 + 1-bromo [l-14q heptane in one flask without isolation of intermed
## Abstract A one‐pot reaction scheme leading to ^14^C‐labeled pargyline (N‐methyl‐N‐ propargylbenzylamine) where in the radioactive label from [^14^C]‐formaldehyde is synthetically incorporated into the methylene group of the propargyl side chain is described. Thus, [^14^C]‐formaldehyde (aqueous s
