[PMID: 38585066 PMCID: PMC10993359 DOI: 10.1021/acsomega.3c10080] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Revised: 02/07/2024] [Accepted: 03/08/2024] [Indexed: 04/09/2024]
Abstract
The highly enantioselective synthesis of (R)-sitagliptin has been achieved through a series of key steps, including the aza-Michael addition and Baeyer-Villiger oxidation. The enantioselective aza-Michael addition involved the reaction of tert-butyl β-naphthylmethoxycarbamate with (E)-1-(4-methoxyphenyl)-4-(2,4,5-trifluorophenyl)but-2-en-1-one, utilizing a quinine-derived C(9)-urea ammonium catalyst under phase-transfer catalytic conditions. The aza-Michael addition successfully introduced chirality to the amine in (R)-sitagliptin with 96% ee. The subsequent Baeyer-Villiger oxidation of the aza-Michael adduct led to the formation of 4-methoxyphenyl ester. Hydrolysis and amide coupling were then employed to construct the amide moiety. Further deprotections were performed to complete the synthesis of (R)-sitagliptin (7 steps, 41%, 96% ee).

MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27196486. [PMID: 36235021 PMCID: PMC9572024 DOI: 10.3390/molecules27196486] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 09/27/2022] [Accepted: 09/27/2022] [Indexed: 11/06/2022]
Abstract
Bonding within the AsF3 crystal is analyzed via quantum chemical methods so as to identify and quantify the pnicogen bonds that are present. The structure of a finite crystal segment containing nine molecules is compared with that of a fully optimized cluster of the same size. The geometries are qualitatively different, with a much larger binding energy within the optimized nonamer. Although the total interaction energy of a central unit with the remaining peripheral molecules is comparable for the two structures, the binding of the peripherals with one another is far larger in the optimized cluster. This distinction of much stronger total binding within the optimized cluster is not limited to the nonamer but repeats itself for smaller aggregates as well. The average binding energy of the cluster rises quickly with size, asymptotically approaching a value nearly triple that of the dimer.
