Benzofused seven-membered heterocycles such as 1,4-benzo[e]diazepines (1,4-BZDs) and 1,4-benzo[e]oxazepines (1,4-BZOs) were efficiently synthesized by Rh-catalyzed hydrofunctionalization of internal alkynes and allenes in good to excellent yields. Th

Hiyama Cross-Coupling Reaction in the Stereospecific Synthesis of Retinoids

Autor: Javier Montenegro, Susana Lopez Estevez, Julian Bergueiro, Carlos Saa

Publikováno v: Organic Letters. 11:141-144

The first application of the Hiyama reaction to the synthesis of retinoids is reported. A range of organosilicon moieties (siloxanes, silanols and three kinds of "safety-catch" silanols) were successfully coupled, under activation, to obtain trans-re
