Background The purpose of this study was to confirm the generalisation of radiofrequency ablation (RFA) in the treatment of benign thyroid nodules (BTN) and to look for a correlation between final shrinkage and some ultrasound (US) findings in a larg

Publikováno v: Tetrahedron. 50:4853-4872

2-Tributylstannyl-2-propen-1-yl acetate (2), which can be easily prepared from ethyl propynoate (5), represents a useful precursor to a variety of 2-tributylstannyl-1-alkenes of general formula 1. Thus, treatment of 2 with complex organocopper specie

Publikováno v: Tetrahedron. 50:12029-12046

Stereoisomerically pure trisubstituted α,β-unsaturated esters of general formula 7 have been efficiently synthesized using two different protocols. The first one involves the palladium(O)/copper(I)-mediated cross-coupling reaction between alkyl ( E
