Methods are reported for the efficient assembly of a series of phenol-derived propiolates, including the parent system 56, and their Au(I)-catalyzed cyclization (intramolecular hydroarylation) to give the corresponding coumarins (e.g., 1). Simple syntheses of naturalproducts such as ayapin (144) and scoparone (145) have been realized by such means, and the first of these subject to single-crystal

water-soluble substrates (glycosidases), whole-protein substrates (proteases), and enzyme inhibition measurements. Hydrolytically labile umbelliferyl esters can be used to assaylipases in this format without background hydrolysis. High throughput and reproducibility were tested by fingerprint analysis of lipases and esterases against 37 different fluorogenic ester substrates. A set of eight fluorogenic unbelliferyl

The suitability of broadband dielectric spectroscopy (DS) as a tool for in-line (in situ) reaction monitoring is demonstrated. Using the esterification of 4-nitrophenol as a test-case, we show that multivariate analysis of time-resolved DS data─collected across a wide frequency range with a coaxial dip-probe─allows reaction progress to be measured with both high precision and high accuracy. In addition
