Lewis base catalysis of bromo- and iodolactonization, and cycloetherification
Denmark, Scott E.,Burk, Matthew T.
, p. 20655 - 20660 (2010)
Lewis base catalyzed bromo- and iodolactonization reactions have been developed and the effects of catalyst structure on rate and cyclization selectivity have been systematically explored. The effects of substrate structure on halolactonization reactions

The strained olefins in trans-cyclooctenes serve as efficient catalysts for halolactonizations, including bromolactonizations and iodolactonizations. The trans-cyclooctene framework is essential for excellent catalytic performance, and the substituents also play important roles in determining efficiency. These results are the first demonstration of catalysis by a trans-cyclooctene.
A Formal Intermolecular Iodolactonization Reaction Based on a Radical-Ionic Sequence
León-Rayo, David F.,Morales-Chamorro, Maricela,Cordero-Vargas, Alejandro
, p. 1739 - 1750 (2016/04/05)
We report herein a method based on a radical-ionic sequence between an allylic alcohol and an α-iodo acid in the presence of substoichiometric amounts of lauroyl peroxide (DLP) to produce an atom transfer radical addition (ATRA) adduct, which subseqently
4-(Dimethylamino)pyridine-catalysed iodolactonisation of γ,δ-unsaturated carboxylic acids
Meng, Chuisong,Liu, Zhihui,Liu, Yuxiu,Wang, Qingmin
supporting information, p. 6766 - 6772 (2015/06/25)
4-(Dimethylamino)pyridine functioned as an excellent catalyst for iodolactonisation reactions of γ,δ-unsaturated carboxylic acids, affording γ-lactones, δ-lactones, or both under neutral conditions at room temperature. The effects of substrate structures
LEAD(IV) ACETATE-METAL HALIDE REAGENTS III. A NEW METHOD FOR THE SYNTHESIS OF TETRAHYDROFURAN, TETRAHYDROPYRAN AND LACTONE DERIVATIVES
Motohashi, Shigeyasu,Satomi, Masakichi,Fujimoto, Yasuo,Tatsuno, Takashi
, p. 2035 - 2039 (2007/10/02)
A new method for the synthesis of tetrahydrofuran, tetrahydropyran and lactone derivatives from γδ-, δε-unsaturated alcohols and βγ-, γδ-carboxylic acids is described.
