The article conveys some information:
An efficient iron-catalyzed asym. [4 + 2] cycloaddition of cyclopentadiene with α,β-unsaturated acyl imidazoles or 2-cinnamoylisoindoline-1,3-dione derivatives was developed to afford the addition products in high yield and selectivity. Interestingly, the absolute structures of the addition products were controlled by the auxiliaries via different coordination modes with the same type of catalyst. In the part of experimental materials, we found many familiar compounds, such as N-Methoxy-N-methylacetamide(cas: 78191-00-1Category: amides-buliding-blocks)
N-Methoxy-N-methylacetamide(cas: 78191-00-1) belongs to anime. Milder oxidation, using reagents such as NaOCl, can remove four hydrogen atoms from primary amines of the type RCH2NH2 to form nitriles (R―C≡N), and oxidation with reagents such as MnO2 can remove two hydrogen atoms from secondary amines (R2CH―NHR′) to form imines (R2C=NR′). Tertiary amines can be oxidized to enamines (R2C=CHNR2) by a variety of reagents.Category: amides-buliding-blocks
