                                    A variety of alpha-(trimethylsilylmethyl)- substituted butyrolactones are readily accessed by a novel tandem ene-reaction/oxidative desilylation of a range of aldehydes, Subsequent functionalisation led to an efficient methodology for the preparation of exo-methylene butyrolactones.
