Abstract
Description
TECHNICAL FIELD
[0001] The present application belongs to the field of organic chemical synthesis, and particularly relates to a method for constructing allyl alcohol derivatives with continuous chiral centers. BACKGROUND
[0002] Building carbon-carbon bond (C-C) is a long-term goal pursued by organic chemists, and asymmetric C-C bond formation reaction can achieve efficient synthesis of chiral molecules, which is an important research frontier. Secondary alcohol with continuous chiral centers is an important structure, which widely exists in various life active substances and is an important building block in organic synthesis, and the development of efficient asymmetric synthesis strategy for this structure is still limited.
[0003] Traditional asymmetric catalytic reaction mostly focuses on the formation of a single chiral center, and the research on the construction of two continuous chiral centers by one-step reaction is relatively less. Limited synthesis methods are the use of chiral substrate-induced diastereoselective synthesis, which requires the pre-synthesis of chiral aldehyde which is difficult to prepare, and the chiral aldehyde is prone to racemization, which is not conducive to storage, and the substrate range and selectivity of the reaction are greatly limited.
[0004] Enantioconvergent catalysis refers to the process of converting racemic substrate into a single chiral product with 100% theoretical yield by one-step reaction under the action of chiral catalyst, and can simultaneously construct two continuous chiral centers, which is an efficient synthesis strategy. As an efficient strategy for synthesizing secondary alcohol with a single chiral center, the asymmetric reductive coupling reaction of aldehyde-yne and the asymmetric addition reaction of aldehyde have been developed, but the enantioconvergent reductive coupling reaction / addition using alpha-branched aldehyde as substrate has not been reported. The difficulty of the reaction lies in the simultaneous control of enantioselectivity, diastereoselectivity and chemical selectivity, and the enantioconvergent reductive coupling reaction of aldehyde-yne also needs to efficiently control the regioselectivity and syn-anti selectivity, which has a high requirement for the catalyst, and suitable conditions need to be found to make the substrate racemize quickly.
[0005] Therefore, there is an urgent need in the art to develop a method for synthesizing allyl alcohol structure with continuous chiral center, which has simple synthesis route, mild reaction condition, high selectivity, strong chiral control ability and wide substrate applicability. SUMMARY
