On the Synthesis and Reactivity of Enantiopure Azetidines

European Journal of Organic Chemistry, 2007
International audienceAbstract β‐Amino alcohols with an ( E )‐vinylsilane moiety were cyclized in the presence of N ‐bromosuccinimide to afford diastereomerically pure azetidines. The chemo‐ and stereoselectivities of this bromocyclization are discussed.
