Synthesis of naturally occurring bioactive butyrolactones: Maculalactones A-C and nostoclide I

Starting from citraconic anhydride (13), a simple multistep (9-10 steps) synthesis of naturally occurring butyrolactones maculalactone A (3), maculalactone B (1), maculalactone C (2) and nostoclide I (4) have been described with good overall yields via di
