Alkyl boronic acids and esters play an important role in the synthesis of C(sp3)-rich medicines, agrochemicals, and material chemistry. This work describes a new type of transition-metal-free mediated transformation to enable the construction of C(sp3)-rich and sterically hindered alkyl boron reagents in a practical and modular manner. The broad generality and functional group tolerance of this method
Provided are a series of novel pyridine or pyrimidine derivatives which inhibit CDK9 and may be useful for the treatment of hyperproliferative diseases. In particular the compounds are of use in the treatment of proliferative disease such as cancer including hematological malignancies such as acute myeloid leukemia, multiple myeloma, chronic lymphocytic leukemia, diffuse large B cell lymphoma, Burkitt's lymphoma, follicular lymphoma and solid tumors such as breast cancer, lung cancer, neuroblastoma and colon cancer.

For the first time, a general catalytic procedure for the cross-coupling of primary amides and alkylboronicacids is demonstrated. The key to the success of this reaction was the identification of a mild base (NaOSiMe3) and oxidant (di-tert-butyl peroxide) to promote the copper-catalyzed reaction in high yield. This transformation provides a facile, high-yielding method for the monoalkylation of amides

Zinc simple: The loading‐dependent zinc‐mediated addition of benzyl bromides to alkynes is the key step for the formation of vinyl bromides. In combination with a palladium‐catalyzed Suzuki cross‐coupling reaction with boronic acids, tri‐ and tetrasubstituted alkenes were obtained in good yields and stereoselectivities in a one‐pot protocol (see scheme).
