Herein, we present a new and efficient convergent solution-phase synthetic strategy for producing peptides containingN-methyl amino acids. Specifically, we have synthesized a model cyclic octapeptide with twoN-methyl amino acids, utilizing an isostearyl-m

The reaction of PhSiCl3 with one equivalent of Li[tBu] at r. t. yielded tBuPhSiCl2 whereas tBu2PhSiCl was only a minor product of the reaction of two molar equivalents Li[tBu] with PhSiCl3 at 60 °C. By contrast,

Photolyses of tert-butyl substituted disilanes 1a-1c, and 1i with C60 result in the formation of 1,16-adduct 2 through silyl radical addition to fullerene. The unusual products, 3, 5, 6 and 7 where the silyl and phenyl groups attached on 1,2-positions of fullerene are also obtained from the reaction of 1d-g and 4. The structures of all these compounds were determined by one- and two-dimensional NMR techniques.
Substituents effects on the addition of silyllithium and germyllithium to C60

Mono-adducts 2 and di-adducts 3 are obtained by the reaction with silyllithium and germyllithium 1 with C60. The selectivities of the products are controlled by electronic and steric effects of the substituents. Formations of 1,4-adduct 4 and dimer 5 can be obtained in the presence of biphenyl derivatives.
