Sha, Chin-Kang,Ho, Wen-Yueh
, p. 2709 - 2710 (1998)
The total synthesis of dimethyl gloiosiphone A 2 was achieved via an α-carbonyl radical spirocyclization.
Intramolecular cycloadditions of vinylketenes to olefins. Part II. The synthesis of a linear annelated triquinane derivative.
Mesmaeker, Alain De,Veenstra, Siem J.,Ernst, Beat
, p. 459 - 462 (1988)
Regioselective formation of vinylketene 3, followed by its stereoselective intramolecular cycloaddition with an olefin, yielded the linear annelated cis-anti-cis triquinane precursor 1.
Tertiary Enamide-Triggered SEAr: Domino Allylation and Enamine-Type Addition
Beltran, Frédéric,Miesch, Laurence

Two unprecedented domino reactions are described, starting from ketospiro-enesulfonamides. By treatment with ZrCl4 and allylsilane, an intramolecular electrophilic aromatic substitution and subsequent allylation is observed. By treatment with TiCl4 and allylsilane, a double enamine-type reaction takes place, thus creating simultaneously four contiguous stereogenic centers diastereoselectively.
Enantioselective Conia-Ene-Type Cyclizations of Alkynyl Ketones through Cooperative Action of B(C6F5)3, N-Alkylamine and a Zn-Based Catalyst
Cao, Min,Yesilcimen, Ahmet,Wasa, Masayuki
supporting information, p. 4199 - 4203 (2019/04/13)
An efficient and highly enantioselective Conia-ene-type process has been developed. Reactions are catalyzed by a combination of B(C6F5)3, an N-alkylamine and a BOX-ZnI2 complex. Specifically, through cooperative
One-pot sequential 1,4- and 1,2-reductions of α,β-unsaturated δ-lactones to the corresponding δ-lactols with CuCl and NaBH 4 in methanol
Matsumoto, Yasunobu,Yonaga, Masahiro
supporting information, p. 1764 - 1768 (2014/08/05)
An efficient, one-pot method for the highly chemoselective synthesis of δ-lactols from α,β-unsaturated δ-lactones using CuCl and NaBH4 in methanol was developed. Georg Thieme Verlag Stuttgart. New York.
