(+)-Hyacinthacines A 1 and A 2 have been prepared from an easily available, advanced intermediate. The non-chiral pool approach features a dichloroketene–enol ether [2+2] cycloaddition and a dihydroxylation or epoxidation as key stereoselective tra

Two tandem flow chemistry processes have been developed. A single palladium-catalysed Heck reaction with ethylene gas provides an efficient synthesis for functionalised styrenes. Through further elaboration the catalyst becomes multi-functional and p

A simple tube-in-tube reactor based on the gas-permeable membrane Teflon AF-2400 was used in the continuous flow reaction of gaseous ammonia with isothiocyanates and one isocyanate. A colourimetric in-line titration technique is also reported as a si

We report a continuous flow, rhodium-catalysed hydro- formylation of various styrenes using a tube-in-tube gas-liquid re- actor. The flow process afforded selectively branched aryl aldehydes in good yields.

A nine-step (longest linear) batch total synthesis of the cyclic hexadepsipeptide (−)-enniatin B is described. The synthesis minimizes precipitation during reaction conditions for adaptability to flow synthesis. The route was used to prepare >100 m
