  Highly Functionalized Cyclopentanes by Radical Cyclization of Unsaturated Bromolactones. 2. A Facile Synthesis of the First Carbaaldohexofuranoses and Their Conversion to Carbapentofuranoses

  摘要：

  A novel type of carbasugars, carbaaldohexofuranoses, has been prepared using a 5-exo-trig radical cyclization of C-2 substituted 2,3-unsaturated 7-bromoheptono-1,4-lactones as the key step. During the cyclization step, two-stereogenic centers were farmed with high stereoselectivity. The lactone moieties of the cyclopentane derivatives were reduced to the alcohols, and the following carbahexofuranoses were synthesized: carba-beta-D-mannofuranose, carba-alpha-L-glucofuranose and 5-amino-5-deoxycarba-alpha-L-glucofuranose. Side chain degradation of the two former compounds gave the carbapentofuranoses: carba-alpha-L-xylofuranose and carba-beta-D-lyxofuranose.

  Abstract Hydrogenolysis of d - glycero - d - gulo -heptono-1,4-lactone penta-acetate gave 3-deoxy- d - gluco -heptonolactone tetra-acetate, which was converted easily into methyl 3-deoxy- d - gluco -heptonate and, thence, into 7-bromo-3,7-dideoxy- and 3,7- dideoxy- d - gluco -heptono-1,4-lactone. Reaction of d - glycero - d - gulo -heptono-1,4-lactone ( 4a ) with hydrogen bromide—acetic acid gave 2

  摘要d-甘油-d-gulo-庚酮-1,4-内酯五乙酸酯的氢解反应制得3-脱氧-d-葡萄糖-庚内酯四乙酸酯，该酯易于转化为3-脱氧-d-葡萄糖-庚酸甲酯。因此，形成7-溴-3,7-二脱氧-和3,7-二脱氧-d-葡萄糖-庚-1,4-内酯。d-甘油-d-gulo-庚-1,4-内酯（4a）与溴化氢-乙酸的反应生成2,7-二溴-2,7-二脱氧-d-甘油-d-偶氮-heptono-1 ，4-内酯（5），其氢解得到7-溴-2,7-二脱氧-（7），2,7-二脱氧-（8）或7-溴-2,3,7-三苯氧基-庚基。 -1,4-内酯（9），取决于条件。将5在水中加热时，得到2,5：4,7-双脱水-d-甘油-d-gulo-庚酸。4a与甲酸在氟化氢中反应生成3,6-脱水-1-甘油-d-古洛-庚酮-1的混合物，4-内酯和3,7-脱水-d-甘油-d-古洛-庚-1,4-内酯。类似的处理将7和8转化为3，6-酐。
