Abstract
Squalestatin 3,4-beta-lactone-4,5-dimethyl ester (8) was reductively ring-o pened to yield squalestatin 3-hydroxymethyl-4,5-dimethyl ester (6) using mi ld reducing conditions (sodium borohydride). Similarly squalestatin 3,4-oxe tane-4,5-dimethyl ester (10) was found to ring-open to 3-iodomethyl squales tatin (15) under the conditions used to cleave the methyl ester functions ( lithium iodide/2,4,6-trimethylpyridine).
