P. Blaney et al., Application of Grignard reagents to the synthesis of tertiary methylaminesvia resin-bound oxyiminium ions, TETRAHEDR L, 41(34), 2000, pp. 6639-6642
The solid-phase synthesis of tertiary methylamines via the nucleophilic dis
placement of benzotriazole Mannich adducts with Grignard reagents using a h
ydroxylamine linker is described. The chemistry is exemplified by the synth
esis of the MAO inhibitor alpha-methylpargyline. Also described is the synt
hesis of the analgesic Tramadol by an alternative one-pot solid-phase Manni
ch reaction. (C) 2000 Elsevier Science Ltd. All rights reserved.
