A One-Pot Iodo-Cyclization/Transition Metal-Catalyzed Cross-Coupling Sequence: Synthesis of Substituted Oxazolidin-2-ones from N-Boc-allylamines

A one-pot iodo-cyclization/transition metal-catalyzed cross-coupling sequence is reported to access various C5-functionalized oxazolidin-2-ones from unsaturated N-Boc-allylamines. Depending on the Grignard reagents used for the cross-coupling, e.g., aryl- or cyclopropylmagnesium bromide, a cobalt or copper catalyst has to be used to obtain the functionalized oxazolidin-2-ones in good yields.

A fit for purpose synthesis of Bruton's tyrosine kinase inhibitor GDC-0852

The development of an expedient synthesis to GDC-0852 (1), a reversible BTK inhibitor drug candidate, is described. The key starting material tricyclic lactam 5 was prepared by an annulation reaction of unprotected piperidine-2-carbaldehyde HCl salt (20) and N-Boc piperidine-2,4-dione 21 in a safe and scalable manner. A highly selective Pd-catalyzed C[sbnd]N coupling of lactam 5 and linker 2a, followed by Suzuki?Miyaura coupling to fragment 8 subsequently provided a direct and convergent access to the penultimate 17. A simple NaBH4 aldehyde reduction completed the synthesis to GDC-0852 (1) in high yield (54% over 3 steps from 5) and purity (99.0 A% HPLC).

One-Pot Three-Component Synthesis of Vicinal Diamines via In Situ Aminal Formation and Carboamination

A synthesis of vicinal diamines via in situ aminal formation and carboamination of allyl amines is reported. Employing highly electron-poor trifluoromethyl aldimines in their stable hemiaminal form was key to enable both a fast and complete aminal formation as well as the palladium-catalyzed carboamination step. The conditions developed allow the introduction of a wide variety of alkynyl, vinyl, aryl, and hetereoaryl groups with complete regioselectivity and high diastereoselectivity. The reaction exhibits a high functional-group tolerance. Importantly, either nitrogen atom of the imidazolidine products can be selectively deprotected, while removal of the aminal tether can be achieved in a single step under mild conditions to reveal the free diamine. We expect that this work will promote the further use of mixed aminal tethers in organic synthesis.
