Summaryr Addition of phenylthiol to a-trimethylsilylmethylene-r-lactones affords a-phenylthio(trhnethylsilyl)methyl-s-lactones which, on treatment with tetrabutylammonium fluorlde and methyl acrylate give the corresponding a-methylene-a-lactones through a one-pot double deblocking process. The a-me
