On July 11, 2009, Robertson, Jeremy; Hall, Michael J.; Green, Stuart P. published an article.Formula: C7H14O3 The title of the article was Stereospecific α-methallylation of hydroxyaldehydes by silatropic ene cyclisation. And the article contained the following:
We describe the thermal rearrangement of aldehydes bearing an α-(allyl- or crotylsilyl)oxy substituent. The transformations are best described mechanistically as intramol. silatropic ene reactions based on stereoselectivity, kinetic and computed transition state data. The overall process constitutes a stereospecific (meth)allylation of α-hydroxyaldehydes, under neutral conditions, in which the hydroxyl protecting group is also the (meth)allylating agent. The experimental process involved the reaction of Methyl 2-hydroxy-3,3-dimethylbutanoate(cas: 121129-31-5).Formula: C7H14O3
