A Br?nsted acid catalyzed, operationally simple, scalable route to several functionalized α-(3-indolyl) ketones has been developed and the long-standing regioisomeric issue has been eliminated by choosing appropriate carbonyls. A readily available and cheap bottle reagent was used as the catalyst. This protocol was also applicable to the synthesis of densely functionalized α-(3-pyrrolyl) ketones. A detailed mechanistic study confirmed the involvement of enolether as a reaction intermediate. Several postsynthetic modifications along with easy access to β-carboline, tryptamines, tryptophols, and spiro-indolenine proclaim the synthetic utility of this powerful building block. On the basis of this concept, functionalized carbazoles were constructed by a cascade annulation strategy.

The following N-2(S)-hydroxy-4-methylpentyl derivatives of Gly-Val-Phe-OMe and Leu-Val-Phe-OMe were designed as analogues of the transition state of the renin-angiotensinogen reaction: N- Gly-Val-Phe-OMe 2 and N-2(S)-hydroxy-
