摘要:Carbohydrate of Formula (A)where R1 is H and n an integer from 1 to 5, is synthesized by reacting, under heating, compound (A0)with HO—(CH2)n—CHâ•?CH2 in the presence of an acid capable of liberating a proton, and cooling the reaction mixture to obtain a cooled mixture comprising compound (A).Carbohydrate of Formula (AAPG)where R2 is a monovalent protecting group, PG is a divalent protecting group and n an integer from 1 to 5, is synthesized by reacting, in the presence of a metal-containing zeolite, compound of Formula (APG)with compound of Formula (A1)where X is —I, —Br, —Cl, —CN, —OTf (Triflate), —OMs (Mesylate), —OTs (Tosylate), methylsulfate, or trichloroacetimidate. Deprotection of compound (AAPG) forms compound (AA)Carbohydrates (A) and (AA) can be coupled with a thiolated linker to form glycoconjugate precursors, which in turn are conjugatable with a carrier material such as a protein, peptide or polypeptide.

摘要:The invention relates to a process for the preparation of compounds of formula I (I) wherein R is mono- or disubstituted lower alkyl, the substituents being selected from halogen and lower alkoxy, with the proviso that said substituents are not present at the carbon atom of the lower alkyl radical R linking the group R to the remainder of the molecule of formula I; R1 is hydrogen, lower alkyl, phenyl or phenyl-lower alkyl; and X is chloro or bromo; which comprises reacting an acetal of formula II, (II) wherein R and R1 are as defined above, with at least one compound of formula R2-X, wherein R2 is hydrogen or X-SO, in which last mentioned case the reaction mixture must contain a catalytically effective amount of N,N-di-lower alkyl-lower alkanoylamide(s) and wherein X is as defined with respect to the compounds of formula I. The compounds of formula I are useful intermediates, suitably for the synthesis of pharmaceutical or fungicidal compounds.
