Hydrotalcite-supported nano-gold (Au/HT) was found to be a highly efficient heterogeneous catalyst for the dehydrogenative synthesis of amidefromalcohol and amine. Amines and alcohols with different structures could be converted into the amides under mild reaction conditions with up to 98% isolated yields. Mechanism exploration suggested that ester might be the reaction intermediate.
The present application describes organic compounds that are useful for the treatment, prevention and/or amelioration of diseases, particularly pyrrolopyrimidine compounds and derivatives are described which inhibit protein kinases. The organic compounds are useful in treating proliferative disease.
This invention relates to substituted bis-amide pyrimidine compounds of Formula (I), which are useful for the treatment of metalloprotease mediated diseases, in particular MMP-13 related diseases.

of secondaryalkyl‐substituted aryl and heteroaryl chlorides challenge both selectivity and functional group tolerance. This contribution describes the use of statistical design of experiments to develop an effective procedure for the preparation of isopropyl‐substituted (hetero)arenes with minimal isopropyl to n‐propyl isomerization. The reaction tolerates electronically diverse aryl chloride coupling
