A versatile synthetic protocol involving the room temperature direct arylation of benzothiazole with a wide variety of iodo(hetero)arenes under palladium-catalyzed conditions and promoted by HFIP as the reaction solvent has been presented herewith. An in-situ one-pot sequential HFIP promoted selective iodination of (hetero)arenes followed by Pd-catalyzed direct arylation of benzothiazole has also been disclosed. Synthesis of PMX 610 (antitumor agent) analog has been disclosed and also CJM 126 (antitumor agent) has been synthesized.

A highly efficient acylative cross-coupling of trialkylboranes with activated amides has been effected at room temperature to give the corresponding alkyl ketones in good to excellent yields by using 1,3-bis(2,6-diisopropyl)phenylimidazolylidene and 3-chloropyridine co-supported palladium chloride, the PEPPSI catalyst, in the presence of K2CO3 in methyl tert-butyl ether. The scope and limitations of the protocol were investigated, showing good tolerance of acyl, cyano, and ester functional groups in the amide counterpart while halo group competed via the classical Suzuki coupling. The trialkylboranes generated in situ by hydroboration of olefins with BH3 or 9-BBN performed similarly to those separately prepared, making this protocol more practical.
