Zhu J, Xiang H, Chang H, Corcoran JC, Ding R, Xia Y, Liu P, Wang YM. Enantioselective and Regiodivergent Synthesis of Propargyl- and Allenylsilanes through Catalytic Propargylic C-H Deprotonation. Angew Chem Int Ed Engl 2024; 63:e202318040. [PMID: 38349957 PMCID: PMC11003844 DOI: 10.1002/anie.202318040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Revised: 02/13/2024] [Accepted: 02/13/2024] [Indexed: 02/15/2024]
Abstract
We report a highly enantioselective intermolecular C-H bond silylation catalyzed by a phosphoramidite-ligated iridium catalyst. Under reagent-controlled protocols, propargylsilanes resulting from C(sp3)-H functionalization, as well the regioisomeric and synthetically versatile allenylsilanes, could be obtained with excellent levels of enantioselectivity and good to excellent control of propargyl/allenyl selectivity. In the case of unsymmetrical dialkyl acetylenes, good to excellent selectivity for functionalization at the less-hindered site was also observed. A variety of electrophilic silyl sources (R3SiOTf and R3SiNTf2), either commercial or in situ-generated, were used as the silylation reagents, and a broad range of simple and functionalized alkynes, including aryl alkyl acetylenes, dialkyl acetylenes, 1,3-enynes, and drug derivatives were successfully employed as substrates. Detailed mechanistic experiments and DFT calculations suggest that an η3-propargyl/allenyl Ir intermediate is generated upon π-complexation-assisted deprotonation and undergoes outer-sphere attack by the electrophilic silylating reagent to give propargylic silanes, with the latter step identified as the enantiodetermining step.

Abstract
Alkene and alkyne difunctionalization is a flexible process that allows the construction of two functional groups simultaneously in one step. On the other hand, carbosilylation, an ingenious difunctionalization pathway to concurrently incorporate both a silyl group and an organic functional group (alkyl, (hetero)aryl, alkenyl, alkynyl and allenyl) across a carbon-carbon multiple-bond system, is achieving immense interest in recent days. This review article provides a decade's update on the discoveries and developments in the synthesis of carbosilylated products from two very important carbon-carbon unsaturated substrates, alkenes and alkynes.

Abstract
Abstract
Conserving the environment is one of the most imperative goals in recent days among the chemists throughout the world. Swiftly increasing the environmental awareness also increases the demand to build new approaches for synthesizing the same active molecules with zero-waste and pollution. In this background, visible-light-mediated synthesis and functionalization of diverse organic compounds has been established as a tremendously successful topic and has achieved a remarkable stage of superiority and efficiency in the last 20 years. Alternatively, organosilicon derivatives are gradually aspiring leaves among chemists because of their significant application on synthetic, medicinal, and material chemistry. In this scenario, the addition of Si–H group to carbon−carbon multiple bonds (alkenes, hetero-arenes, alkynes, allenes, carboxylic acids, enynes, and dienes) provides an extremely step- and atom-efficient method to obtain silicon-containing compounds. Several attempts for the development of mild, robust, and efficient green protocol were taken in the last two decades. In spite of substantial advancement/research on C–Si bond formation using transition metal catalysis, a green and metal-free approach is highly essential considering its application in the field of medicine and with respect to environmental aspects as well. In this article, we will summarize the reports considering suitable visible-light-mediated metal-free silylation of C–C multiple bonds that includes alkenes, hetero-arenes, alkynes, allenes, enynes, and dienes.
