A biomass involved rhodium-catalyzed carbonylative synthesis of furfuryl esters and tertiary amides has been developed. 5-Hydroxymethylfurfural (HMF) was used as both substrate and CO surrogate for the first time in a carbonylation reaction, and both alkyl and aryl iodides were tolerated well to afford the desired furfuryl esters in moderate to good yields. In addition, furfural was also utilized as a CO source for the synthesis of tertiary amides. A variety of tertiary amides were obtained in moderate to excellent yields with good functional groups compatibility. Notably, tertiary amines were used as the amine source through a C[sbnd]N bond cleavage pathway in the absence of additional oxidant.

Bruton's tyrosine kinase (BTK) is a promising drug target for the treatment of multiple diseases, such as B-cell malignances, asthma, and rheumatoid arthritis. A series of novel aminotriazines were identified as highly selective inhibitors of BTK by a scaffold-hopping approach. Subsequent SAR studies of this series using two conformationally different BTK proteins, an activated form of BTK and an unactivated form of BTK, led to the discovery of a highly selective BTK inhibitor, 4b. With significant efficacy in models in vivo and good ADME and safety profiles, 4b was advanced into preclinical studies.
