Reaction of polymer bound tryptophan with a variety of aldehydes and k
etones under Pictet-Spengler like conditions was found to produce 1,2,
3,4-tetrahydro-beta-carbolines in excellent yield. The straightforward
, easily automated chemistry and the availability of numerous commerci
al aldehydes and ketones makes this approach ideal for combinatorial c
hemistry application. Copyright (C) 1996 Elsevier Science Ltd
