A rationally designed amphiphile containing a hydrophobic Hantzsch ester and a hydrophilic phosphate ester was able to form vesicles in aqueous solution, and resulted in the first example of a NO-responsive drug delivery system.

The 1,3-dicarbonyl compounds are important building blocks to obtain products with various biological activities and technological applications. In this work, we used a simple transesterification method to develop fatty acetoacetates in a solvent-free medium using a green catalyst, sulfamic acid (NH2SO3H), under microwave irradiation. The experimental results demonstrate good yields in a short reaction time (13?min), which makes this method an efficient approach to synthesize fatty acetoacetates from a wide range of saturated, unsaturated, and polyunsaturated long chain fatty alcohols, and ricinoleic derivatives. Experiments of recycling of the catalyst were performed and no decrease in catalytic activity of sulfamic acid was observed.

Treatment of methyl or ethyl β-keto esters with primary, secondary, or tertiary alcohols in the presence of a catalytic amount of hexamethylenetetramine results in good to high yields of the corresponding esters. Georg Thieme Verlag Stuttgart.
