Ketenes as Privileged Synthons in the Syntheses of Heterocyclic Compounds Part 2: Five-Membered Heterocycles

Prescribed drugs containing nitrogen heterocycles: an overview

“…23 We are interested in heterocyclic chemistry, 24 especially those containing nitrogen atom. [25][26][27][28][29][30][31][32][33] We are interested in heterocyclic chemistry, 24 especially those containing nitrogen atom. [25][26][27][28][29][30][31][32][33] In recent years, our group has also focused on the applications of name reactions in the total synthesis of natural products containing nitrogen heterocycles, showing diverse biological activities.…”

[25][26][27][28][29][30][31][32][33] In recent years, our group has also focused on the applications of name reactions in the total synthesis of natural products containing nitrogen heterocycles, showing diverse biological activities. [34][35][36][37][38][39][40][41][42] Armed with these experiences, in this review we try to highlight the medical usages and selected synthetic pathways of approved and market purchasable prescribed medications, containing nitrogen based-heterocycles.…”

Applications of Dainshefsky's Dienes in the Asymmetric synthesis of Aza‐Diels‐Alder Reaction

“…We are interested in heterocyclic chemistry and their asymmetric synthesis . We have recently reviewed the applications of DA and HDA reactions in the total synthesis of natural products ,.…”

QM study on regioselectivity in the synthesis of pyrimido[4,5-b][1,4]benzothiazines: kinetic and thermodynamic point of view

“…Also we are interested in heterocyclic chemistry [24][25][26][27][28][29][30][31] and more focused on nitrogen heterocycles such as pyrimidine [32,33] and 1,2,4-triazines [34]. There are two main important concepts in heterocyclic chemistry, tautomerism and regioselectivity.…”
