An efficient method for alkylâallyl cross-coupling between ethers and a 9-BBN-derived allylborane catalyzed by indium(I) triflate has been developed. The allylborane proved to be essential to obtain the desired products in high yields. The reaction displayed good substrate scope including high functional group tolerance.
This invention relates to compounds of formula I
their use as positive allosteric modulators of mGlu5 receptor activity, pharmaceutical compositions containing the same, and methods of using the same as agents for treatment and/or prevention of neurological and psychiatric disorders associated with glutamate dysfunction such as schizophrenia or cognitive decline such as dementia or cognitive impairment.

“Design” of Boron-Based Compounds as Pro-Nucleophiles and Co-Catalysts for Indium(I)-Catalyzed Allyl Transfer to Various Csp3-Type Electrophiles

日期:2011.9.5
our work highlights for the first time the correlation between the Lewis acidity of “electrophilic” boron‐based compounds and their “nucleophilic” reactivity in Csp3–Csp3 couplings, catalyzed by a “soft” low‐oxidation main group metal. In addition, we also report several applications of these methodologies to the selective synthesis of various carbohydrate derivatives.
