On July 22, 2009, You, Shuli; Xia, Jibao published a patent.Computed Properties of 93476-46-1 The title of the patent was Method for synthesizing 3-haloindolizine. And the patent contained the following:
The invention relates to the method for preparation of 3-haloindolizine derivatives of formula I. Compounds of formula I wherein R1 and R2 are independently H, C1-16 alkyl, C3-16 cycloalkyl, amino and derivatives,C1-16 alkoxy, halo, C1-16 alkanoyl, C5-10 heterocyclyl, C5-10 heteroaryl, etc.; are claimed. Compounds of formula I were prepared via halogenation of indolizines with copper halides. The method has the advantages of broad scope of suitable substrates, low cost, mild reaction conditions, easy operation, high efficiency, and high selectivity. The experimental process involved the reaction of Ethyl indolizine-1-carboxylate(cas: 93476-46-1).Computed Properties of 93476-46-1
