• An Alternative Method for Regioselective, Anomeric Deacylation of Fully Acylated Carbohydrates
  作者：Jian Zhang、Pavol Kováč

  日期：1999.1

  Ethylenediamine in admixture with acetic acid has been found useful to selectively effect the title conversion and can be of general utility. Reaction rates anomeric deacylations effected with this reagent are slower than with reagents introduced earlier, resulting in easier control and greater selectivity of deprotection.

  The compounds of formula (1), wherein n is an integer from 0 to 4; R1 is a radical selected from the group consisting of H, CH 3 , CH 2 -CH 3 , C(CH 3 ) 3 , COOH, CONH 2 and C=CH; R2, R3, R4 and R5 are radicals independently selected from the group consisting of H, F, Cl, Br, (C 1 -C 3 )-alkoxyl and (C 1 -C 4 )-alkyl; and R6 is a radical selected from the group consisting of H, F, Cl, Br, (C 1 -C 3 )-alkoxyl, (C 1 -C 4 )-alkyl, R7, CH=CH-R7 and O-CH 2 -R7; wherein R7 is phenyl or phenyl mono- or independently di-substituted with F, Cl, Br, (C 1 -C 3 )-alkoxyl or (C 1 -C 4 )-alkyl, exhibit a similar chemotactic index to that of amygdalin (natural product whose chemotaxis profile is similar to that of peptide T) and, consequently, are useful for treating inflammatory and/or allergic dermatophathies, such as psoriasis, and are especially much less toxic than amygdalin.
