A -Benzoyloxypyridinium chloride (72), prepared from pyridine oxide and benzoyl chloride, reacts with silver phenylacetylide selectively at position 2 to afford 2-(phenylethynyl)pyridine (73). The bromine atom of the tetrahydro-l,4-oxazin-2-one 74 is replaced by an alkynyl group on treatment with stannanes 75 (R = hexyl or Ph) the products 76 are transformed into ( S)-amino acids 77 by catalytic hydrogenation. ...

The reactivity of the amino radical has not yet been investigated. Alkaline hypochlorite oxidation, known in the pyridine series to yield azo derivatives (155,156). and photolysis of N,N-dichloro derivatives, which may be obtained by action of sodium hypochlorite on amino derivatives in acidic medium (157). should provide interesting insight on this reactivitv.

Constitution. When coniine is distilled with zinc dust or heated with silver acetate/ a new base, coiiyrine, CgH N, differing from coniine by six atoms of hydrogen, is formed. This on oxidation yields pyridine-2-carboxylic acid and, since it is not identical with 2-isopropylpyridine, must be 2-propylpyridine (I). When coniine is heated with hydriodic acid at 300° it yields w-octane (II). These and other observations due mainly to A. W. Hofmann, made it clear by 1885 that coniine was probably a-propylpiperidine (III), and this has been amply confirmed by other reactions of the alkaloid and by syntheses. Thus, Wolffenstein showed that on oxidation with hydrogen peroxide, coniine is converted into amino-w-propylvaleraldehyde (IV) ...
