skeletons and employing various combinations of five key transformations provides an easy access to most of the naturally occurring Annonaceous acetogenins. A particular emphasis is given to the dominant structural feature that appears in more than 40% of the known acetogenins. This is a linear, ten-carbon skeleton comprising two adjacent tetrahydrofurane rings flanked with two hydroxyl groups. Efficient
