Transformation of a carbonyl functional group into thiocarbonyl has been an important
interest to synthetic organic chemists for many years. Two reagents, phosphorus …

Triazoles are an important class of heterocyclic compounds not only as a core scaffold but
also as a benzo-fused (triazolopyridines and triazolopyrazines are well-known examples) or …

A general approach has been developed for the one-pot synthesis of 3, 4, 5-trisubstituted 1,
2, 4-triazoles from secondary amides and hydrazides via triflic anhydride activation followed …

Solid-phase organic synthesis is a rapidly expanding area of synthetic chemistry that is
being widely exploited in the search for new medicinally important compounds using …

3, 4, 5-Trisubstituted 1, 2, 4-triazoles were synthesized in solution from various thioamides
and hydrazides in smooth experimental conditions leading to peptidomimetic scaffolds. This …

The synthesis of two series of monocyclic and bicyclic trifluoromethylated 4, 5-dihydro-1, 2, 4-
triazin-6 (1 H)-one derivatives based on (3+ 3)-annulation of methyl esters derived from …

This is the seventh comprehensive survey in an ongoing annual review series in
combinatorial chemistry. 1 The format remains largely the same as in past years with …

Abstract The 1H‐pyrazole‐3‐carboxylic acids 2 were converted via reactions of their acid
chlorides 3 with some semi‐and thiosemicarbazide derivatives into the corresponding new …

A series of arylpiperazinylbutyl derivatives of 4, 5‐dihydro‐1, 2, 4‐triazine‐6 (1H)‐ones was
designed and synthesized according to the new solid‐supported methodology. In this …

Lactone analogues of 3‐substituted oxindoles (= 1, 3‐dihydro‐2H‐indol‐2‐ones) and
nonbenzoid oxa‐analogous isoindigoid or nonbenzoid isoindigoid dyes were prepared by …
