The reaction of [4-g1utamic acidjdeamlnc-l-carba-oxytocin (lb) with diazoalkanes yielded the corresponding methyl ester Ie and ethyl ester ld. Alternatively, the methyl ester was prepared by means of carbodiimide or thionyl chloride, or by treating the caesium salt of compound Ib with methyl iodide. [2-0~Methyltyrosine, 4-glutamic acid methyl esterjdeamino-f-carba-oxytccin (liz) was also synthe...

This circumpolar dataset of the comatulid (Echinodermata: Crinoidea) Promachocrinus kerguelensis (Carpenter, 1888) from the Southern Ocean, documents biodiversity associated with the specimens sequenced in Hemery et al. (2012). The aim of Hemery et al. (2012) paper was to use phylogeographic and phylogenetic tools to assess the genetic diversity, demographic history and evolutionary relationshi...
