A nucleophilic cleavage reaction of 2,2,5,5,8,8-hexamethyl-2,5,8-trisilanona-3,6-diyne, I, with several bases, occurs rapidly at room temperature in both polar and non-polar solvents. An attack occurs exclusively at the central silicon regardless of the steric requirements of the bases (alkyllithium). The major products from the reaction of I with tert-butyllithium followed by hydrolysis were 2,2,5,5,6,6-hexamethyl-2,5-disilahepta-3-yne, II, and 2,2,5,5-tetramethyl-2,5-disilahexa-3-yne, VI.

A major focus of the Leighton group has been the development of efficient, scalable and step-economical reactions towards our goal of expanding the structural variants of medicinally relevant non-aromatic polyketide natural products. Over the last few years the Leighton group has developed a novel mode of strained-silane Lewis acid activation with the use of weakly-coordinating anionic catalysts. Hyper-coordinate silicates with unprecedented levels of reactivity have facilitated previously unattainable late stage complex fragment couplings. A novel method of chiral anion catalyzed nucleophilic addition to α- and β-diketones has been explored. Finally, an operationally straightforward, efficient and direct β-ketoaldehyde allylation methodology will be discussed.
