Equilibrating mixtures of allylic azide-containing allylic alcohols or allylic 2-tolylsulfonylacetic esters undergo Johnson–Claisen or Ireland–Claisen rearrangement reactions to give unsaturated γ-azidoesters and -acids, respectively. Decarboxylation of the acids under basic conditions gives azidosulfones, with moderate to high diastereoselectivity.
平衡的含烯丙基叠氮化物的烯丙基醇或烯丙基2-甲苯磺酰基磺酸酯的混合物会经历Johnson-Claisen或Ireland-Claisen重排反应,分别得到不饱和的γ-叠氮酯和-酸。在碱性条件下酸的脱羧得到叠氮基砜,具有中等至高的非对映选择性。
