✦ Synopsis

Seven 6,

[1,51diazocines 2 with different substituents at position 13 have been prepared from o-(triphenylphosphoranylideneamino)benzaldehyde I and the corresponding aliphatic and aromatic primary amines in yields ranging from 40 to 80%. The molecular and crystal structures of componds 2d (R = 4 H3C-C6H 4) and 2e (R = 4 H3CO-C6H 4) have been determined by X-Ray analysis. Compound 2d crystallizes as a racemate while compound 2e crystallizes as a unique enantiomer (absolute configuration R,R).
