This report describes two straightforward synthetic methodologies to obtain α-CF3-isoserine, a new α,α-disubstituted β-amino acid, from α-(trifluoromethyl)acrylic acid. The routes involve the synthesis of five-membered cyclic sulfates (using sulfuryl chloride) or sulfamidates (using the Burgess reagent) from the corresponding chiral diols, which are obtained by a catalytic asymmetric dihydroxylation
该报告介绍了两种简单的合成方法,得到α-CF 3 -isoserine,一个新的α , α二取代的β氨基酸,从α-(三氟甲基)丙烯酸。这些路线涉及从相应的手性二醇合成五元环硫酸盐(使用硫酰氯)或氨基磺酸盐(使用Burgess试剂),它们是通过催化不对称二羟基化(AD)反应获得的。
