Synthesis of trans-16-triazolyl-13α-methyl-17-estradiol diastereomers and the effects of structural modifications on their in vitro antiproliferative activities.

Erzsébet Mernyák et al.

The Journal of steroid biochemistry and molecular biology, 150, 123-134 (2015-04-08)

Novel 16-triazoles in the 13α-estrone series were synthesized via Cu(I)-catalyzed azide-alkyne cycloaddition of the two diastereomeric (on C-16 and on C-17) 16-azido-13α-estra-1,3,5(10)-trien-17-ol 3-benzyl ethers with substituted phenylacetylenes. The new heterocyclic derivatives were evaluated in vitro by means of MTT assays

Efficient one-pot synthesis of novel and diverse furo[2,3-d] pyrimidinediones and thioxofuro[2,3-d] pyrimidineones by the rhodium (II) pivalate-catalyzed reactions of cyclic diazo compounds.

Krishna Bahadur Somai Magar et al.

Molecular diversity, 17(4), 679-691 (2013-08-03)

The rhodium(II)-catalyzed reactions of cyclic diazo compounds derived from barbituric acid or thiobarbituric acid with arylacetylenes and styrenes were examined. These reactions provide a rapid synthetic route to the preparation of a variety of novel and diverse furo [2,3-d pyrimidine-2,4-diones

Microwave-assisted palladium-catalyzed highly regio-and stereoselective head to head dimerization of terminal aryl alkynes in water.

Buxaderas E, et al.

Royal Society of Chemistry Advances, 4(87), 46508-46512 (2014)
