## Abstract A useful synthetic approach to carbon‐11 labelled 1,4‐dihydropyridines is described. Carbon‐11 labelled calcium channel antagonists ^11^C‐Nifedipine, ^11^C‐Nisoldipine, ^11^C‐Nitrendipine and ^11^C‐CF~3~‐Nifedipine were synthesized by a modified Hantzsch method using protected carboxy f
## Abstract Derivatives of alanine, α‐[2‐^11^C]aminoisobutyric acid 1a and α‐(N‐methyl)‐[2‐^11^C]aminoisobutyric acid 1b were prepared for the __in__‐__vivo__ study of amino acid transport phenomena by positron‐emission‐tomography (PET). Compounds 1a and 1b were obtained by a Zelinski‐Stadnikoff va
