The catalytic addition of terminal alkynes to carbonyls has proven to be a powerful tool in the preparation of complex synthetic targets. This includes a wide range of bioactive natural products and pharmaceutical compounds, for which synthetic efficiency is of the utmost importance. This chapter provides a snapshot of the synthetic utility of these alkynes. The use of a stabilized alkynyl nucleophile...
A comprehensive and up-to-date overview of alkyne chemistry, taking into account the progress made over the last two decades. The experienced editors are renowned world leaders in the field, while the list of contributors reads like a "Who's Who" of synthetic organic chemistry. The result is a valuable reference not only for organic chemists at universities and in the chemical industry,...
Alkyne is one of the fundamental functional groups that established the foundation of organic chemistry. The smallest member of this family, acetylene, is a moderately common chemical in the universe, often in the atmosphere of gas giants. The higher members of alkynes are generally derived from the smaller homologs via alkyne homologation processes of the terminal alkynes, while some alkynes are...
In this chapter, an overview of redox isomerization is presented and organized along the line of catalysts. The first example of a transition‐metal‐catalyzed isomerization of primary propargyl alcohols to enals was reported by Ma and Lu in 1989 using a Ru complex 15 which required long reaction times at high temperatures. The reaction was envisioned to proceed by hydrometallation‐dehydrometallation...
