Efficient Synthesis of β‐Primeverosides as Aroma Precursors by Transglycosylation of β‐Diglycosidase from Penicillium multicolor
摘要:
The enzyme activity transferring a beta-primeverosyl unit was found from culture filtrates of Penicillium multicolor IAM7153 and was useful for synthesizing a series of beta-primeverosides via a beta-primeverosyl transfer reaction in an aqueous-organic biphasic system. With the acceptors benzyl alcohol, 2-phenylethanol, and ( Z )-3-hexenol, the enzyme induced the transfer products benzyl, 2-phenylethyl, and ( Z )-3-hexyl beta-primeverosides in high yields of 51% to 70% based on the donor added. When geraniol and eugenol were used as acceptors, the corresponding geranyl and eugenyl beta-primeverosides were obtained in lower yields of 8% to 12%. The enzyme was an excellent tool for producing naturally occurring beta-primeverosides on a mmol scale.
