Stereospecific Access to Trisubstituted Enol Ethers from Vinylsilanes
摘要:
The reaction of RCH=CHSiMe3 (R: alkyl or aryl) with IPy2BF4/HBF4 and a set of representative alcohols affords the corresponding addition products as a single regio- and stereoisomers in good yield. Subsequent dehydroiodination with DBU furnishes silyl-substituted enol ethers. (C) 1997 Elsevier Science Ltd.

A convenient, novel synthesis of β-ketosilanes based on (Z)-1-bromo-1-alkenylboronate esters is developed. α-Bromo-(Z)-1-alkenylboronate esters readily available using literature procedures smoothly undergo a reaction with trimethylsilylmethyllithium in tetrahydrofuran to provide the corresponding ‘ate’ complexes. These ‘ate’ complexes will undergo intramolecular nucleophilic substitution reactions
