  Carbocyclic analogues of d-ribose-5-phosphate: Synthesis and behavior with 5-phosphoribosyl α-1-pyrophosphate synthetases

  摘要：

  The synthesis of cyclopentyl and cyclopentenyl analogues of the cr-anomer of D-ribose-5-phosphate from D-ribonolactone and D-ribose is described. These analogues, which have the same absolute configuration as D-ribose-5-phosphate, were incubated with PRPP synthetases in an attempt to prepare the corresponding carbocyclic PRPP analogues. The carbocyclic ribose-5-phosphate analogues were found to be inhibitors, rather than substrates, for 5-phosphoribosyl alpha-1-pyrophosphate synthetases of both bacterial and human origin. The inhibitory behavior of the analogues is described. Copyright (C) 1996 Elsevier Science Ltd

  The cyclocondensation reactions between L-alpha-amino acid phenylhydrazides and 2,3-O-isopropylidene-L-erythruronolactone in the presence of a catalytic amount of p-toluenesulfonic acid afforded diastereomerically pure (3S,6R,7R,7aS)-3-substituted-6,7-isopropylidenedioxy-1-phenylamino-dihydro-1H-pyrrolo[1,2-a]imidazole-2,5(3H,6H)-diones, which were converted by acidic hydrolysis with MeOH-HCl into their corresponding optically active (35,6R,7R,7aS)-3-substituted-6,7-dihydroxy-l-phenylamino-dihydro-1H-pyrrolo[1,2-a]imidazole-2,5(3H,6H)-diones in good yields.
