An expansion of methodologies aimed at the formation of versatile organonitriles, via the intramolecular aminocyanation of unactivated alkenes, is herein reported. Importantly, the need for a rigid tether in these reactions has been obviated. The ease-of-synthesis and viability of substrates bearing flexible backbones has permitted for diastereoselective variants as well. We demonstrated the utility

Reactions of p-(pent-4-enyloxy)aniline with salicylaldehyde containing versatile substituents in the positions 3 and 5 in an open system without solvent at 130°C afforded a series of (N-aryl)salicylaldimines, which with TiCl2(OPr-i)2 formed complexes of titanium(IV) dichloride L2TiCl2.

Soluble polymer synthesis: An improved traceless linker methodology for aliphatic CH bond formation

A traceless linker was developed on a soluble polymer support. The methodology allows for the facile attachment of molecules possessing an alkyl halide appendage. The coupled molecule can be further functionalized before subsequent cleavage via a two-step oxidation-reduction sequence. This sequence allows for the synthesis of molecules containing no trace of the linker and the formation of a new C-H bond. (C) 1997, Elsevier Science Ltd.
