Amino Acids in the Synthesis of Heterocyclic Systems a Novel Synthesis of Fused Pyridinones
TL;DR: In this paper, the synthesis of fused enamines with a methyl group at α-position in respect to ring nitrogen atom is presented, where enamines are transformed with 2-phenyl-5 (4H)-oxazolone into corresponding intermediates, which cyclize into azinopyridinones.

The chemistry of formamide acetals
R.F. Abdulla,R.S. Brinkmeyer +1 more
TL;DR: The formamide acetals as mentioned in this paper have been used in two main categories of reactions, namely alkylation and formylation, and are used in the synthesis of esters from acids, ethers and thioethers from phenols and aromatic and heterocyclic thiols.

Methylation of heterocyclic compounds containing NH, SH and/or OH groups by means of N,N-dimethylformamide dimethyl acetal
TL;DR: In this paper, selective methylation of some compounds containing both SH and NH groups was performed to give first the S-methyl and subsequently the S,N-dimethyl derivatives.
