Mono-N-ethylated h-amino acid esters are obtained in high yields using reductive amination procedures. Formation of imine is achieved by excess of acetaldehyde, followed by removal of acetaldehyde and reduction by NaBH(OAc) 3 . The elaborated one-pot synthesis allows for the efficient synthesis of s
Flavones were prepared using a one-pot procedure starting from the corresponding 2 0 -hydroxyacetophenones. The latter were treated with 3 equiv of aroyl chloride in wet K 2 CO 3 /acetone (1% w/w water) to afford a good yield of flavone and a smaller amount of 3-aroylflavone. Evidence was obtained t
