The reaction proceeded similarly to peptide immobilization, with a stock solution of FAM alkyne 6-isomer being used instead of the peptide stock.

In the presence … WebThe reaction was discovered in the early 1900s by the Russian chemist Alexei Yevgrafovich Favorskii. [1] When the carbonyl is an aldehyde (R"=H), a rearrangement can occur to generate enone, although the secondary propargylic alcohol can be isolated in some cases. [2] When this rearrangement is catalyzed by an acid, it is called Meyer ... cummins albany
