Efficient synthesis of 2-mono- and 2,3-disubstituted indoles via palladium-catalyzed oxidation of amino alcohols.

[摘要]：Amino alcs., obtained by reaction of N-protected o-toluidines or 2-ethylanilines with aldehydes, were deprotected and cyclized in the presence of Pd(PPh3)4 to give indoles (I; R = H, Me; R1 = alkyl, cyclohexyl, phenethyl).
