## Abstract The synthesis of 1‐(2‐^13^C)‐cyclopropyl‐4‐phenyl‐1,2,3,6‐tetrahydropyridine (8) is reported. Attempts were first made to prepare labeled cyclopropylamine via a cyclopropanation/Curtius rearrangement sequence, but the yields were too modest to be suitable for the synthesis of a labeled

Abstract
The introduction of several ^13^C‐atoms in the alkane chain is described. A maximum number of compounds, with up to six ^13^C labels, are obtained with a minimum of different reactions.

## Abstract 17α‐Hydroxyprogesterone (__**2**__) was converted to an enol‐lactone __**8**__ in which the 20‐oxo group was selectively protected as an ethylene acetal. The enol‐lactone __**8**__ was subjected to Claisen condensation with phenl acetate‐1,2‐^13^C~2~ in the presence of sodium hydride, w
## Abstract This report describes the synthesis of carbon‐13 labeled n‐octyltrichloro silane from ^13^C‐barium carbonate. The product is labeled at the 8‐position of the alkyl chain.

## Abstract Two complimentary syntheses of selectively ^15^N‐ or ^13^C‐labelled malachite green hydrochloride were developed in order to provide labelled ligands for structural studies of RNA aptamer/ligand complexes. The ^15^N‐ and ^13^C‐labelled versions of the dye have been used in NMR studies t
