------------
b-Phenylethylamines, Indolines and Isoquinolones via Hydroamination of
Styrenes by Microwave Irradiation

Julio A. Seijas,* M. Pilar Vázquez-Tato,* M. Montserrat Martínez
Synlett 2001 No. 6, 875–877
pdf



Abstract:
Microwave irradiation promotes hydroamination of styrenes.
This method can be used as a direct way of producing different
kinds of bioactive compounds: open chain compounds like
ß-phenylethylamines or cyclized products like indolines or isoquinolones.

Key words: amination, domino reaction, indoline, isoquinolone,
microwave heating, nucleophilic addition, phenethylamine


Comment
Ning over at the WD had this to say about this procedure......
Quote:

aniline reacted with propenylbenzene in the microwave for 10 minutes to give N-phenylamphetamine in 42% yield. Aniline : propenylbenzene : KOtBu = 10:1:1 (Synlett 2001, 875)

So all those ramblings about "heat a propenylbenzene and ammonia to a few hundred degrees under pressure, get amphetamines" are not all that wrong? Shocked

Who wants to try with isosafrole and benzylamine? Debenzylation to yield MDA is no problem...

The pet monkey would gladly be happy to do this if a debenzylation proceedure can be posted. Smile

This would also be a nice way to make TMA-2.
