A new one-pot method, for the synthesis of polysubstituted pyrrolo[3,4-d]pyridazinones, is presented. The protocol consists in cascade reactions performed in the same media: (i) the thermal in situ pyrrole formation by the reaction of vinyl azides with 1,
Synthesis of 3,4,5-trisubstituted isoxazoles by the 1,3-dipolar cycloaddition reaction of α-azido acrylates and aromatic oximes

A novel, one-pot, cascade reaction sequence featuring the 1,3-dipolar cycloaddition reaction of α-azido acrylates and aromatic oximes was developed. This procedure provides an efficient, straightforward and metal-free method for the synthesis of 3,4,5-trisubstituted isoxazoles under mild reaction conditions.

Functionalized spiro-tetrahydro-β-carbolines were formed by an efficient gold(I)-catalyzed rearrangement reaction of alkynylaziridine indoles. The reaction involved a Friedel-Crafts type intramolecular reaction of alkynylaziridine indoles, following by hydroamination of aminoallene intermediate.

The syntheses of alkaloids including indoles, indolines, tetrahydroquinolines, dihydroquinazolinones and quinazolinones have been accomplished in moderate to excellent yields via [Fe(F20TPP)Cl] catalyzed intramolecular C-N bond formation using aryl azides as nitrogen source.
AMINO ACIDS AS SYNTHONS FOR HETEROCYCLES. FORMATION OF 1,2,4-TRIAZINE DERIVATIVES

, p. 393 - 405 (2007/10/02)
Transformation of the amino group of amino acids into an amidine and subsequent treatment with hydrazine leads to 1,2,4-triazine-6(1H)-ones.The method described is a new synthetic approach.Unsaturated amino acids gave imidazol-5-one derivatives after the
