Abstract

The title compounds, readily prepared from allyltrimethoxysilane, pyrocatechol, and triethylamine, react with aldehydes regiospecifically and chemoselectively without catalyst under mild conditions: the allylation takes place even in protic solvents such as ethanol. ... Much effort has been devoted to the regiospecific allylation of carbonyl compounds and efficient methods are highly desirable. Tetraco-ordinate allyltrialkylsilanes are excellent reagents for the ...
