Autocleavage ofO-Isopropylidene ProtectedO-Phosphono- andO- Thionophosphono Esters of Sugars
摘要:
Phosphorylation of D-glucose, D-galactose, D-fructose, glycerol and xylitol acetals with diethoxy- or diphenoxy(thiono)phosphoryl chloride gave the corresponding esters. A novel method of partially and fully deprotecting these compounds, which we have called "autocatalytic cleavage", was effected by simply refluxing in water. Antifungal and insecticidal properties of these compounds are presented.

O-Thallium(I) salts are shown to promote a variety of rapid, high-yield, substitution reactions at an anomeric, a primary, or a secondary position of carbohydratederivatives. Syntheses are described of phosphates, phosphites, sulfites, and xanthic ester derivatives. Preparation of the thallous salt involves a facile exchange between thallous ethoxide and an alcohol group of the carbohydrate. The substitution

the tested alcohols, oxidomolybdenum tetrachloride (MoOCl4) was found to be the most efficient with a negligible background reaction mediated by triethylamine (Et3N). The new catalytic protocol can be applied to the chemoselective phosphorylations of primary, secondary and tertiary alcohols as well as the substitution‐free phosphorylations of allylic, propargylic, and benzylic alcohols. Functionalized
