Abstract
Vrije Universiteit Brüssel, Pleinlaan 2, B-1050 Brussels, Belgium a Department of General and Organic Chemistry, Faculty of Applied Sciences b High Resolution NMR Centre Abstrac t Tetra-n-butylbis(2,3:4,6-di-isopropylidene-2-keto-L-gulonato)distannoxane has been synthesized and characterized by ID Ή , 1 C and l l 7 S n NMR, 2D ' H 1 3 C HMQC and HMBC NMR spectroscopy, and electrospray mass spectrometry. It was found moderately active in vitro against seven human tumoural cell lines. Introduct ion The one-pot synthesis of dibutyltin carboxylates [l] used to prepare the title compound involves two steps: a transient tetra-n-butyldipropoxydistannoxane is prepared first
