This contribution reports the first chemoselective, stereospecific, and living polymerization of polar divinyl monomers, enabled by chiral ansa-zirconocenium catalysts through an enantiomorphic-site controlled coordination-addition polymerization mechanis
Potassium Base-Catalyzed Michael Additions of Allylic Alcohols to α,β-Unsaturated Amides: Scope and Mechanistic Insights

We report herein the first KHMDS-catalyzed Michael additions of allylic alcohols to α,β-unsaturated amides through allylic isomerization. The reaction proceeds smoothly in the presence of only 5 mol% of KHMDS to afford a variety of 1,5-ketoamides in high yields. Mechanistic investigations, including experimental and computational studies, reveal that the KHMDS-catalyzed in-situ generation of the enolate from the allylic alcohol through a tunneling-assisted 1,2-hydride shift is the key to the success of this transformation.

Hydroiodination of 2-propynamides leading stereoselectively to (Z)-iodopropenamides was achieved under mild conditions at room temperature by the combined use of zinc iodide and tert-butyl iodide. Similarly, the use of zinc bromide in the presence of tert
Radical Cyclisation in Heterocycle Synthesis. Part 1. Sulfanyl Radical Addition-Cyclisation of Dienylamides for Lactam Synthesis

, p. 19 - 26 (2007/10/02)
A new method for the synthesis of five- to eight-membered lactams by sulfanyl radical mediated-cyclisation of dienylamides is described.The sulfanyl radical addition-cyclisation of the dienylamide 1 was systematically investigated under four different conditions and was found to give the cyclised lactams 2-6 in 54-79percent yield.The stereo- and regio-selectivity of sulfanyl radical addition-cyclisation was established from the preferential formation of the trans-cyclised lactam 3 and also from the substituent effects in the cyclisation of the dienylamides 11-18.The sulfanyl radical mediated addition-cyclisation was successfully applied to the construction of the six- and eight-membered lactams 28a, b.

The sulfonyl radical-promoted cyclizations of 1,6-unsymmetrical dienes can be totally chemoselective.The addition of tosyl halides to various 1,6-dienes bearing both a nucleophilic and an electrophilic double bond clearly indicates that this attractive pr
