Abstract
Processes for production of phloroglucinol or derivative thereof. An aspect of the present disclosure relates to an enzymatic process for production of phloroglucinol or derivative thereof from polyphenol. The present disclosure also relates to a process for production of phenolic derivatives. Accordingly, another aspect of the present disclosure relates to an enzymatic process for production of phenolic derivatives from polyphenol. The processes of the present disclosure affords facile and environment friendly production of phloroglucinol or derivative(s) thereof and/or phenolic derivative(s).
Claims27
A process for production of phloroglucinol or a derivative thereof, comprising contacting a polyphenol with a hydrolase enzyme.
A process for production of a phenolic derivative of Formula C
- wherein R4 is selected from H, OH and —OR6, R6 being a sugar moiety;
- and R5 is selected from OH, C1-C4 alkyl group and —OR7, R7 being a C1-C4 alkyl group or a sugar moiety;
- and n ranges from 0-5;
- comprising contacting a polyphenol of Formula A or Formula B
- wherein R1, R2 and R3 are independently selected from H, C1-C4 alkyl group and a sugar moiety;
- R4 is selected from H, OH and —OR6, R6 being a sugar moiety;
- R5 is selected from OH, C1-C4 alkyl group and —OR7, R7 being a C1-C4 alkyl group or a sugar moiety;
- and n ranges from 0-5.
- with a hydrolase enzyme.
