Synthesis of cis-vinyltrimethylstannanes and cis-vinylpinacolboronates in a two-step highly regio and stereoselective process
摘要:
A highly efficient two-step regio and stereoselective method for the synthesis of both cis-vinyltrimethylstannanes and cis-vinylpinacolboronates is described. This method takes advantage of the known lithium/tellurium exchange pathway providing a versatile alternative to known literature methods The methodology presented demonstrates compatibility, for example, with substrates bearing oxygen functionality in comparison to previously reported methods of cis-selective hydrostannylation (i.e., ZrCl4) (C) 2009 Elsevier Ltd.

A stereoselectivesynthesis of Z‐vinyl selenides through the reaction of sodium selenide with organic halides, followed by the addition of alkynes was developed.

Herein we describe a novel stereoselective synthesis of cis-vinylstannanes employing the widely established Li/Te exchange pathway. In contrast to previously reported methods of cis-selective hydrostannation (i.e., ZrCl4), this method demonstrates compatibility toward oxygenated substrates.
