Treatment of methyl 4,6- O -benzylidene-2,3-dideoxy-3-nitro-α- d - erythro -hex-2-enopyranoside with phenylacetonitrile afforded adducts having the d - manno ( 2 and 3 ) and d - gluco configurations ( 4 and 5 ), the isoxazole 6 , the cyano alkene 7 , and the nitro alcohols 9 and 10 . Similar reaction of the β anomer 11 gave adducts having the d - gluco configuration ( 12 and 13 ) and the nitro alcohol
摘要用苯乙腈处理甲基4,6-O-亚苄基-2,3-二脱氧-3-硝基-α-d-赤型-hex-2-烯吡喃糖苷得到d-manno(2和3)和d-葡萄糖构型(4和5),异恶唑6,氰基烯烃7和硝基醇9和10。β端基异构体11的类似反应得到具有d-葡萄糖构型(12和13)和硝基醇14的加合物。描述了在加合物的苯乙腈取代基上形成6和初步构型分配的机理。
