A stereodivergent route, starting from d-glyceraldehyde derivative, employing Wittig olefination–Claisen rearrangement protocol is reported for the synthesis of six novel carbahexofuranoses—carba-α-d-glucofuranose, carba-β-d-altrofuranose, carba-α-d-allofuranose, carba-β-d-idofuranose, carba-α-d-galactofuranose and carba-β-d-talofuranose in enantiomerically pure form.
据报道,从d-甘油醛衍生物开始,采用Wittig烯烃化-Claisen重排方案的立体发散途径可合成六种新的碳呋喃呋喃糖酶,即carba-α-d-葡萄糖呋喃糖,carba-β-d-铝呋喃糖,carba-α-d-d-。对映体纯净形式的异呋喃糖,氨基甲酸酯-β-d-呋喃二糖,氨基甲酸酯-α-d-半乳糖呋喃糖和氨基甲酸酯-β-d-塔拉呋喃糖。
