A novelmethod has been developed for the synthesis of benzyl alkyl ethers in 25–85% yields via the reaction of toluene with alcohols in a CCl4 medium catalyzed by Et3N-activated VO(acac)2.
Imidamide (amidine) analogs that can inhibit the activity of sphingosine kinase 1 and sphingosine kinase 2 (SphK1 & SphK2) are provided. The compounds can prevent angiogenesis in tumors.

Synthesis of benzyl alkyl ethers was performed in high yields by intermolecular dehydration of benzyl and primary, secondary, tertiary alcohols under the effect of copper containing catalysts. The formation of benzyl alkyl ethers occurs with participation of benzyl cation.
The invention relates to inhibitors of Sphingosine Kinase enzymatic activity, and methods of treating diseases and disorders by administering inhibitors of Sphingosine Kinase enzymatic activity.

Replacement of a dimethyl amino group of the amidobis(amine) nickel(II) pincer complex (1), [((N2N)-N-Me)-Ni-Cl], by a pyrrolidino group resulted in a new nickel(II) pincer complex (2), [((PNNN)-N-yr-N-Me)Ni-Cl]. Complex 2 is an efficient catalyst for Kumada and Suzuki-Miyaura cross-coupling of nonactivated secondary alkyl halides, while complex 1 is largely inactive. The significant activity difference is tentatively attributed to a minimal structural difference, which leads to a more hemilabile ligand.
