Pd-catalyzed C3-selective allylation of indoles with allyl alcohols promoted by triethylborane.

Under palladium catalysis, Et3B nicely promotes allyl alcohols to undergo C3-selective allylation of indoles and tryptophan; the yields range 75-95%.

Pd.Et3B-catalyzed alkylation of amines with allylic alcohols.

A combination of catalytic amounts of Pd (0.05 mmol) and Et3B (0.3 mmol) promotes allylic alkylation of primary and secondary aromatic and aliphatic amines (1.0 mmol) by the direct use of allylic alcohols, providing tertiary amines in excellent yields under mild conditions (room temperature approximately 50 degrees C).
