The reaction of carboxylic acids with alcohols in the presence of diethyl azodicarboxylate and 3-methylbenzothiazole-2-selone gave the corresponding esters with retention of configuration at the alcoholic carbon atom.
Disclosed is the use of the reactive components of the inverse electron-demand Diels Alder reaction for chemical masking and unmasking in vitro. This can be applied in complex chemical reactions and, particularly in the synthesis of biomolecules, e.g. on solid supports. The reactive components are a dienophile, particularly a trans-cyclooctene, and a diene, particularly a tetrazine.
