An eco-friendly, simple, mild, chemo selective and highly efficient procedure for the acylation of primary and secondary amine function in various structurally and electronically aliphatic and aromatic compounds affording their corresponding N-Ac derivatives is developed. Mild conditions, simplicity and easier work-up are the main advantages of this method.

A alternative strategy for the synthesis of glycosides, using glycosidase enzymes, has been developed. In contrast to previous procedures, this new method uses limiting amounts of the acceptor alcohol substrate in combination with an excess of the glycosyl donor. Using this procedure, a series of mono- and disaccharides have been prepared.

Observations concerning the synthesis of substituted tryptaminederivatives starting from indoles and 1,n-amino alcohols via the borrowing hydrogen process are discussed. This catalytic, single-step, and modular approach to tryptamines and homotryptamines allows the synthesis of branched and nonbranched tryptamines as well as tryptamine-based natural products such as psilocin, bufotenin, and serotonin
