β¦ Synopsis
In accord with our predictions (1) , methionine-derived Cl-units are usually found attached to aromatic rings (2) or aliphatic chains (3). The only reported examples of a Cl-unit 'in a carbon chain are in the ethyl group of the side-chain of sitosterols (4) which was predicted

2 reacts with fluorosilanes, e.g. with F3SiC6H5, in the molar ratio 1 2 to give disubstituted ("monomeric") products containing an eight-membered ring. ['] Reaction in the molar ratio 1 : 1 leads to a derivative 4 of the novel bicyclic system 1,3,5,7-tetraaza-2,4,6,8,9-pentasilabicyclo[3.3.l]nonane
The alkaloid pinidine ( 2) is acetate-derived, the administration of [l-%]acetate to Pinus jeffreyi plants affording pinidine which is labelled equally on alternate carbons 2. It is presumed that the alkaloid is formed from a Cl0 poly-B-keto acid (l\_) produced by the condensation of a 'starter' ace
