Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 71432-55-8, Name is tert-Butyl N,N’-diisopropylcarbamimidate, SMILES is CC(/N=C(OC(C)(C)C)/NC(C)C)C, in an article , author is Alotaibi, Majdah R., once mentioned of 71432-55-8, Recommanded Product: tert-Butyl N,N’-diisopropylcarbamimidate.
Herein, a divergent synthesis of a variety of 2 alpha- and 5 alpha-substituted furan derivatives from 2-hydroxy-1,4-diones is reported. By using appropriate substrates and an acid catalyst, the reactions occurred selectively through cyclization/1,6-conjugate addition or cyclization/Friedel-Crafts-type cascade reactions. A broad range of nucleophilic reagents (>10 types for the 1,6-conjugate addition for 5 alpha substitution and >20 types for the Friedel-Crafts-type cascade reaction for 2 alpha substitution), including alcohols, amides, furan, thiophene, pyrrole, indole, phenols, and many others, can successfully participate in the reactions, providing a universal strategy for a diversity-oriented synthesis of alpha-substituted furan derivatives. Deuteriation experiments and DFT calculations were carried out to support the proposed reaction mechanisms. Antifungal activity experiments revealed that products with an indole or 4-hydroxycoumarin core substituted at the 2 alpha position showed moderate activities against Rhizoctorzia solani and Botrytis cinerea, respectively.
