This invention belongs to the field of biochemical technology, specifically disclosing a 6′- O A whole-
cell biosynthesis method for caffeoyl
arbutin and its analogues includes the following steps: using aromatic carboxylic acids and vinyl acetates as substrates, performing a transvinylation reaction under
palladium catalyst and base conditions to prepare aromatic vinyl esters; using the prepared aromatic vinyl esters as acyl donors, ... β
Arbutin, using acyl acceptors, undergoes an aromatic
acylation reaction in an
organic solvent with whole cells of
Aspergillus oryzae as a catalyst to yield the 6′- O Caffeoyl
arbutin or its analogues. This invention develops a two-step whole-
cell catalytic method for the efficient and sustainable synthesis of CA and its analogues. The synthesized compounds exhibit potent inhibitory activity against
mushroom tyrosinase. This invention pioneers a novel green biosynthetic pathway for
tyrosinase inhibitors, demonstrating significant application potential in the
food preservation and
cosmetics industries.
