- W55652607 abstract "The syringolides, specified by avirulence gene D from Psendomonas syringae. elicit a disease reaction only in soybean cultivars carrying the Rpg4 disease resistance gene. In order to identify structural features important for clicilor activity and construct highly labeled elicitor-active probes, several syringolide derivatives were synthesized (Tsurushima et al. 1996). The synthesis of syringolidc derivatives were started from changing the hemikclal group of syringolide 1 to ketal group (Fig. I). Syringolidc I was reacted with the corresponding alcohol in the presence of dry Dowex/HCI. All ketal derivatives had no clicilor activity in soybean leaves. Esterification of the C-4’ hydroxyl group on syringolide 1 was performed using N.N’-dicyclohcxylcarbodiimide(DCC), l-(3-dimcthylaminopropyl)-3-clhylcarhodiimidc methiodide (EDCI) or 4-(dimethylamino) pyridine (DMAP). However the esterification reaction destroyed the syringolidc ring system. Since syringolidc ketals were stable to esterification using base catalysis, (C-3)-O-bcnzyl syringolidc I was esterified with 3.4.5-trimethoxyphenylacctic acid. 3-(4-mcthoxyphenyl)propionic acid or succimc anhydride. After the reaction the protecting group was removed by hydrogenation. Hemikelal esters of syringolidel elicited the HR only in soybean cotyledon carrying Rpg4. whereas the ketal esters were inactive. Hemikelal esters were also active elicitors of glyceollin in soybean coiyledons. while ketals had no elicitor activity. 4-(3.4.5-Trinicthoxyphenylacetyl)syringolidc I was unlimited by adding AgOCOCF3 and iodine in anhydrous CH2Cl2to produce 4’-(2-indo-3,4,5-trimcthoxyphcnylacctyl) syringolide 1 in 95 % yield.KeywordsPropionic AcidEsterification ReactionSoybean CultivarDisease ReactionAvirulence GeneThese keywords were added by machine and not by the authors.
