Rhodium-Catalyzed Annulation of Vinylated Tyrosines with Internal Alkynes to Access Oxepine-Mounted Unnatural Tyrosines and Its Peptide Late Stage Functionalization

Autor: Narendra Dinkar Kharat, Chikkagundagal K. Mahesha, Kiran Bajaj, Rajeev Sakhuja

Publikováno v: Organic letters. 24(37)

A Rh(III)-catalyzed [5+2] annulation of vinyl tyrosines with symmetrical and unsymmetrical internal alkynes was achieved, furnishing a series of oxepine-mounted tyrosine-based unnatural amino acids. In addition, the chemical applicability of the deve

Effect of SODs on Mechanical and Wear Behaviours of Alumina and Alumina–Titania APS Coatings on AISI304

Autor: K. B. Sachidananda, Arjun Dey, S. Sunil Kumar, K. Mahesha

Publikováno v: Journal of The Institution of Engineers (India): Series D. 102:47-54

Atmospheric plasma spraying (APS) technique was utilized to deposit pure alumina and alumina–titania-based composite coatings on the 304 stainless steel substrates. Here, in the present work, one of the important process parameters viz. stand-off d
