Br?nsted-base-catalyzed remote cascade reactivity of 2,4-dienones-asymmetric synthesis of tetrahydrothiophenes

This study demonstrates that the remote cascade functionalization of 2,4-dienones can be realized by employing Br?nsted base catalysis. The developed cascade involving 1,6-addition followed by the intramolecular aldol reaction provides a straightforward a
Intermolecular Phosphite-Mediated Radical Desulfurative Alkene Alkylation Using Thiols

We report herein the development of a S atom transfer process using triethyl phosphite as the S atom acceptor that allows thiols to serve as precursors of C-centered radicals. A range of functionalized and electronically unbiased alkenes including those containing common heteroatom-based functional groups readily participate in this reductive coupling. This process is driven by the exchange of relatively weak S-H and C-S bonds of aliphatic thiols for C-H, C-C, and S-P bonds of the products formed.
Synthesis of 2-Aminoazoles from Thioesters via α-Heterosubstituted Ketones by Copper-Mediated Cross-Coupling
Kobayashi, Hiroyuki,Eickhoff, John A.,Zakarian, Armen
, p. 9989 - 9999 (2015/11/03)
Facile synthesis of a variety of α-heterosubstituted ketones under mild conditions was achieved by copper-mediated cross-coupling of thioesters with functionalized organostannanes. Application of this coupling methodology provided a concise pathway for the conversion of carboxylic acids to 2-aminoimidazoles, 2-aminothiazoles, and 2-aminooxazoles via thioesters in practical yields.
