Monosaccharides and products resulting therefrom

摘要

The invention provides novel compounds of the formula: <IMAGE> wherein B is alpha - or beta - and represents a hydrocarbyl group in which the alpha -carbon atom is activated by a suitable blocked or unblocked functional group rendering it susceptible to oxidation. The compounds are useful as intermediates in the preparation of prostaglandins and prostaglandin analogues. The invention also provides a stereospecific method of producing these intermediates.
