Hydrogenation of linear ω-azido-pentafluorophenyl esters gives cyclic peptides containing 14-, 21-, 28-, 35-, 56- and 70-membered ring lactams from oligomers derived from ε-amino acids in excellent to moderate yields with a lack of racemisation dur

Circular dichroism studies on a series of linear oligomers derived from a protected 6-amino-6-deoxy-D-galactonate (an ε-amino acid) indicated a predisposition to form a rigid structure in solution, which is comparable to a β-sheet composed of L-ami

High intensity ultrasound has been applied to the preparation of polyurethanes from a number of diisocyanates and diols. In all cases, the sonochemical reactions proceeded faster in the early stages and led to higher molecular weight polymers. The ef

Hydrogenation of linear ω-azido-pentafluorophenyl esters from mixed oligomers of 6-amino-6-deoxy-D-galactonic acid (or 6-amino-6-deoxy-D-mannonic acid) and 6-aminohexanoic acid gives cyclic peptides containing 14-, 28- and 42-membered ring lactams.

The formation of the 28-membered ring cyclo[(6-amino-6-deoxy-D-galactonic acid)4] by cyclisation of a protected open chain fully hydroxylated nylon 6 linear tetramer in modest yield provides the first example of a new class of carbopeptoid-cyclodextr

High-intensity ultrasound has been applied to the ring-opening polymerisation of delta-valerolactone and epsilon-caprolactone catalysed by dibutyl tin dilaurate. Sonication was found to accelerate the polymerisation. In the case of delta-valerolacton
