Synthesis of carbazol‐4‐ones, 3,4‐dihydrocyclopental‐indol‐1‐one, and indole derivatives by a Fe/AcOH‐mediated intramolecular reductive N‐heteroannulation of 3‐hydroxy‐2‐(2‐nitrophenyl)enones is demonstrated. The same protocol has been extended to access indolocarbazolone and indoloquinolone derivatives.

PdCl(2) can catalyze the acetylation of primary and secondary alcohols with vinyl acetate. The reaction is selective and mild with high yields. Tertiary alcohols, phenols and amines are unaffected under these reaction conditions.

It has been observed that a catalytic amount (0.1 mol%) of cerium(IV) triflate afforded geminal diacetates from aldehydes with acetic anhydride in toluene at ambient temperature. Ketones are not affected under these reaction conditions. The reaction is rapid and mild with good to high yields.

Different fused pyrrole derivatives are efficiently synthesized by the present new cheap method.
