Abstract
The acid-catalysed decomposition of the un-saturated diazomethyl ketones (1–3) leads to the cyclo-pentenone derivatives (4–6), respectively; this reaction, in conjuction with the Reformatsky addition-dehydra-tion sequence, leading to βγ-unsaturated acids, repre-sents a new cyclopentenone annelation scheme.Keywords
