A variety of dibutyltin polyethers have been synthesized employing the interfacial polymerization technique. The products are polymers with degrees of polymerization ranging from 60 to 390. Infrared spectral and mass spectral results are consistent with the proposed structure. The products show good inhibition of a variety of cancer cells including those associated with bone, breast, prostrate, and...
Candida antarctica lipase (Novozym 435) showed good to high enantioselectivity in the acylation of aliphatic and aromatic secondary alcohols (E = 38-166), and higher enantioselectivity in the hydrolysis of their corresponding acetates than other lipases tested, including lipases AY and MY (Candida sp.) and lipases PS, AK and LIP (Pseudomonas sp.).
