Keto thiolactones

A preliminary report has been published on a stereoselective approach to medium-sized ketolactones involving an alumina-catalysed cyclization of epoxydihydropyrans followed by addition of singlet oxygen and thermal decomposition of the resulting dioxetan (Scheme 26). Previous studies (1, 134, 135) have been extended to a synthesis of keto-thiolactones. ... [Pg.100]

A convenient synthesis of medium-sized keto-thiolactones has been developed. The key step is a photosensitized oxygenation of bicyclic thioenol ethers (Scheme 35). A study of thio-oxalates as dithiabutadienes has been carried out, and some unusual sulphur heterocycles have been prepared (Scheme 36). [Pg.282]
