Dialkyl arylphosphate esters have been synthesized in improved yields by the reaction of dicyclohexylamine salts of substituted phenols with dialkyl hydrogen phosphite and carbon tetrachloride. The reaction proceeds through the corresponding phosphorochloridates. Dialkyl arylphosphate esters form a
Glycosylation of the readily accessible benzyl 2-acetamido-6-O-benzyl-2-deoxy-3-O-[(R)-1-(methoxycarbonyl)ethyl]-alpha- D- glucopyranoside with 3,4,6-tri-O-acetyl-2-deoxy-2-phthalimido-beta-D-glucopyranosyl chloride (2), using the silver triflate method in the absence of a base, afforded 65-70% of t
## Abstract A multistep synthesis of a mannose 6โphosphonateโbased glycolipid is described involving (1) a oneโcarbon chain elongation at the 6โposition of mannose, followed by (2) phosphonation, using tris(trimethylsilyl)phosphite. This method was shown to e efficient and provides a general route
