Neue Bildungsweise der Oxazole [PDF]

open access: greenBerichte der deutschen chemischen Gesellschaft, 1896
Bei dem Versuch, das Benzaldehydcyanhydrin mit Acetochlor-hydrose in atherischer Losung durch Salzsaure zu einem Glucosid zu vereinigen, wurde ein schon krystallisirtes chlorhaltiges Product gewonnen, an dessen Bildung die Acetochlorhydrose nicht betheiligt ist.

Performance Analysis Of Regularized Linear Regression Models For Oxazolines And Oxazoles Derivitive Descriptor Dataset [PDF]

open access: goldpublished International Journal of Computational Science and Information Technology (IJCSITY) Vol.1, No.4, November 2013, 2013
Regularized regression techniques for linear regression have been created the last few ten years to reduce the flaws of ordinary least squares regression with regard to prediction accuracy. In this paper, new methods for using regularized regression in model choice are introduced, and we distinguish the conditions in which regularized regression ...

Naturally Occurring Oxazole-Containing Peptides [PDF]

open access: yesMarine Drugs, 2020
Oxazole-containing peptides are mostly of marine origin and they form an intriguing family with a broad range of biological activities. Here we classify these peptides on the basis of their chemical structure and discuss a number of representatives of each class that reflect the extraordinary potential of this family as a source of new drugs.
