WebUnfortunately, the dehydration of the terminal 3º-alcohol (last step) was less selective and gave appreciable amounts of the gem.-disubstituted double bond. This synthesis may be compared with a more recent synthesis (2001) reported by French chemists at CNRS. Some features of their synthesis will be displayed above by clicking on the diagram.

Three ( Z )-BPT derivatives ( 1 – 3 ) showed stronger tyrosinase inhibitory activities than kojic acid; in particular, 2 was to be 189-fold more potent than kojic acid. Webdouble bond gives another resonance-stabilized carbocation: This carbocation is also the conjugate acid of a ketone. Loss of a proton gives the ketone product. The hydration of alkynes is a useful way to prepare ketones provided that the starting ma-terial is a 1-alkyne or a symmetrical alkyne (an alkyne with identical groups on each end of having wakened crossword
