Derek Lowe’s blog has a recent post entitled A Downside to Oxetane Acids which picks up on a recent article[cite]10.1021/acs.orglett.2c01402[/cite] describing how these acids are unexpectedly unstable, isomerising to a lactone at a significant rate without the apparent need for any catalyst. This is important because these types of compound occur frequently in the medicinal chemistry literature.
