systems (ring-opening of four-membered rings; (ii) intramolecular assistance, or both factors); (iii) use of moisture-sensitive and/or activation reagents (up to 2–3 equivalents; borate esters, dialkylformamide dialkyl acetals, AlCl3, AlMe3, HCl). Examples of transamidation from the Stahl's group provided an elegant possibility of preparing amides under mild † This paper is dedicated to Prof. Victor
