Catalytic ring‐opening of bio‐sourced non‐strained lactones with aromatic amines can offer a straightforward, 100 % atom‐economical, and sustainable pathway towards relevant N‐aryl amide scaffolds. Herein, the first general, metal‐free, and highly efficient N‐aryl amide formation is reported from poorly reactive aromatic amines and non‐strained lactones under mild operating conditions using an organic

text] A general synthesis of acylsilanes from the corresponding morpholine amides and silyllithium species is described. The use of morpholine amides is economical and prevents over-addition by the silyl nucleophile. The procedure cleanly affords acylsilanes in good yields and circumvents the use of stoichiometric copper(I) cyanide typically employed to synthesize these compounds from acid chlorides.

The reaction of a lactone or an ester with organoaluminum species generated from DIBAL–H–H2NR or DIBAL–H–HNR1R2·HCl complexes provided efficient methods for preparation of amides. Conditions were defined for the preparation of both secondary and tertiary amides, including Weinreb amides in excellent yields.
