As for vinyl acetate, vinyl propionate led to a 100 % conversion within 48 h (Table .). However, the conversion slightly decreased with longer chain lengths, reaching 74 % and 69 % with vinyl hexanoate and vinyl octanoate, respectively. Interestingly, a slightly lower conversion was obtained with vinyl chloroacetate compared to vinyl propionate, suggesting that the presence of the larger chlorine atom appears to limit the ability of the enzyme to carry out the reaction. It remains plausible that near-complete conversion could be achieved with a longer reaction time, however, this hypothesis was not investigated in the present study. Lastly, it is worth noting that, as demonstrated by the obtained NMR spectra, no acylation occurred on the secondary alcohol in these experiments. The structure of the ester derivatives was further confirmed by LC-MS (Table .).
