The methods may be used to convert a wide variety of aldehydes (e.g., aryl, alkyl, or alkenyl aldehydes) to C-1 deuterated aldehydes under mild reaction conditions without functionality manipulation.
专利号:US-11117893-B2 优先权日:2018-09-24 标题 :Methods for preparation of substituted pyridines and related novel compounds 发明人:WATKINS EDMOND BLAKE; UREDI DILIPKUMAR; MOTATI DAMODER REDDY 权利人:WATKINS EDMOND BLAKE; UREDI DILIPKUMAR; MOTATI DAMODER REDDY; UNION UNIV 摘要:The present invention relates to novel methods of preparation of substituted pyridines and the compounds produced therefrom. In particular, the present invention provides efficient methods for the construction of diversely substituted pyridines, with varying substitution patterns under simple and metal-free conditions with high atom- and pot-economy and excellent functional group tolerance, and which are useful for the synthesis of natural products.
专利号:WO-8911536-A1 优先权日:1988-05-27 标题:Microbial biocatalyst for production of terpenic aldehydes 发明人:DAVIS KAREN JOHANNA; BEST DAVID JOHN; BURFIELD ANTHONY GRAHAM; TAYLOR FRANK; TALBOT JANE STELLA 权利人:NOVALAL LTD 摘要:An active biocatalyst for converting alpha-pinene epoxide to terpenic aldehydes useful in perfumery, e.g. formula (I), is produced by growing a microorganism, preferably Pseudomonas fluorescens NCIB 40043, to late log phase in a medium containing carbohydrate (e.g. glucose) as the carbon source, and adding alpha-pinene. The resulting culture comprises active biocatalyst which is brought into contact with alpha-pinene epoxide for aldehyde synthesis.
专利号:US-2023250042-A1 优先权日:2020-09-29 标 题 :Curcusone diterpenoids and uses thereof 发明人:DAI MINGJI; CUI CHENGSEN; CAI ZHONGJIAN; ADIBEKIAN ALEXANDER; DWYER BRENDAN 权利人:PURDUE RESEARCH FOUNDATION 摘要:The present disclosure provides the first asymmetric total synthesis and target identification of the curcusone natural products. The novel convergent synthesis is built upon a cheap and abundant chiral pool molecule (8) and features a thermal [3,3]-sigmatropic rearrangement and an FeCl3-promoted global hydrolysis/adol condensation cascade to rapidly construct the critical cycloheptadienone core. By performing chemoproteomics with the alkyne probe 37, we identified the previously “undruggableâ€? oncogenic protein BRAT1 as a key cellular target of 1d. Furthermore, 1d inhibits BRAT1 in cancer cells, thereby reducing cancer cell migration, increasing susceptibility to DNA damage, and inducing chemosensitization to the approved drug etoposide. Compound 1d is the first known small-molecule inhibitor for BRAT1, a master regulator of the DDR and DNA repair. Composition matters and methods of uses are within the scope of this disclosure.
