History of Cyclotides

Cyclotides are head-to-tail cyclic peptides in plants Cyclotides are plant-derived peptides of approximately 30 amino acids. They have the characteristic structural features of a head-to-tail cyclized backbone and a cystine knot arrangement of their three conserved disulfide bonds. Their unique structural features lead to exceptional stability. This and their amenability to chemical synthesis have made… Continue reading History of Cyclotides

The Bingel reaction in fullerene chemistry

Bingel fullerene The Bingel reaction in fullerene chemistry The Bingel reaction in fullerene chemistry is a fullerene cyclopropanation reaction to a methanofullerene first discovered by C. Bingel in 1993 with the bromo derivative of diethyl malonate in the presence of a base such as sodium hydride or DBU.[1] The preferred double bonds for this reaction on the fullerene surface are the shorter bonds at the junctions of two hexagons (6-6 bonds) and the driving… Continue reading The Bingel reaction in fullerene chemistry
