A method of producing an ester linked carbohydrate-peptide conjugate is provided comprising: (a) providing a vinyl ester amino acid group, and (b) reacting the vinyl ester amino acid with a carbohydrate acyl acceptor in the presence of an enzyme, to produce thereby an ester-linked carbohydrate-peptide conjugate. Also provided are ester linked carbohydrate-peptide conjugates obtainable by such methods.

The present invetion relates to a process for preparation of a product compound of formula (I), where R1 is an acyl group. The process involves reacting a starting compound of formula (II), with an activated acyl donor compound in the presence of a non-chemically modified lipase, under conditions effective to produce the product compound.

Efficient and scalable Cu(II)‐mediated enol esterification methodology of carboxylicacids from alkenyl boroxines and boronic acids is presented. The reaction shows a wide scope in aliphatic and aromatic carboxylicacids in combination with several alkenyl boroxines. In the case of 2‐substituted alkenyl boroxines the double bond configuration was fully retained in the enol ester product. Also N‐hydroxyimides
