The synthesis of 6-deoxy-1,2-O-isopropylidene-6-(triorganostannyl)-α-D-glucofuranose (4) is reported. Compound 4a (R = R′ = Me), reacts with halogens (I2 and Br2) or with Pd(COD)CI2 to give 4 (R = Me, R = X (X = I, Br or Cl) and MeY [Y = I, Br or Pd(CODCl]. The unsaturated sugar, 5,6-dideoxy-l,2-O-isopropylidene-α-D-xylo-hex-5-enofuranose (6) is formed in the reaction of 4a(-R = R′ = Me) with CF3CO2H
报道了6-脱氧-1,2-O-异亚丙基-6-(三有机甾烷)-α- D-葡萄糖呋喃糖的合成(4)。化合物4a(R = R'= Me)与卤素(I 2和Br 2)或与Pd(COD)Cl 2反应生成4(R = Me,R = X(X = I,Br或Cl) MeY [Y = I,Br或Pd(CODCl)。反应中生成不饱和糖5,6-二脱氧-1,2-O-异亚丙基-α-D-二甲苯基-六-5-呋喃呋喃糖(6)含CF 3 CO 2 H,ClC(O)Z(Z = Ph,Me或OEt),SO 2或(NC)2 CC(CN)2的4a(-R = R'= Me)
