α-Methylene β-Lactones as Masked Allenes and Allene Equivalents: Some Selected Chemical Transformations

Article abstract of DOI:10.1021/jo00020a017

Selective chemical transformations have been performed on a number of α-methylene β-lactones to illustrate that these highly functionalized heterocycles serve as useful building blocks in organic synthesis.Thus, thermal decarboxylation of these "masked al
