waste product in the Heck reaction, was found to act as a key catalyst in the practical one-pot Heck-dehydration reaction. A concisesynthesis of indiacen A was accomplished in 92% overall yield using a protecting-group-free and redox-neutral strategy. In this synthesis, a novel one-pot reaction with high regio- and stereo-selectivity was developed and further application in the total synthesis of other

A concisesynthesis of TMC-205 was accomplished in two steps via a protecting-group-free (PGF) and redox-economical strategy. In this approach, a high yield Pinnick oxidation and a practical Heck-dehydration reaction with high atom economy as well as a high regio- and stereo-selectivity (E-isomer) were used and further applied to the total synthesis of its active analogues. This newly established route
