1,3-Dipolar cycloaddition reactions of acyl phosphonates with nitrile oxides: synthesis of phosphonate-containing dioxazole derivatives
Autor: Sidika Polat-Cakir
Publikováno v: Phosphorus, Sulfur, and Silicon and the Related Elements. 196:461-467
New phosphonate-containing five-membered heterocyclic dioxazole derivatives are synthesized via 1,3-dipolar cycloaddition reactions of nitrile oxides used as dipole with acyl phosphonates under basic conditions. Herein, acyl phosphonates take part in

Enantioselective synthesis of new chiral 2-aziridinyl phosphonates and studies of their biological activities
Autor: Duygu Şimşek, Nurzhan Beksultanova, Sidika Polat Cakir, Nurten Altanlar, Özdemir Dogan, Hasan Karabıyık
A new series of chiral aziridinyl phosphonates has been synthesized and evaluated for antibacterial and antifungal activities. For the synthesis, a Gabriel-Cromwell reaction was used to form aziridinyl phosphonates in 52-83% yield. In order to evalua

Publikováno v: The Journal of Organic Chemistry. 74:7529-7532
A diastereoselective synthesis of the tetrahydropyranochromene ring system common to several natural product isolates of Alpinia blepharocalyx is reported. We have shown that a stereochemical preference exists for a syn configuration between the anom

Autor: Sidika Polat Cakir, Keith T. Mead
Publikováno v: Tetrahedron Letters. 47:2451-2454
Suzuki coupling reactions between 2,4,6-trialkoxyphenylboronic acids and enol triflates have been found to occur in excellent yield, while the use of an enol tosylate failed to give any of the desired product. This coupling reaction has led to the sy
