Brisdon, Brian J.’s team published research in Tetrahedron in 1993 | CAS: 59410-82-1

H-Phg-OEt.HCl(cas: 59410-82-1) belongs to esters. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. Product Details of 59410-82-1

Brisdon, Brian J.; England, Richard; Reza, Khalid; Sainsbury, Malcolm published an article on January 29 ,1993. The article was titled 《Monofunctional chiral crowns. Part 1》, and you may find the article in Tetrahedron.Product Details of 59410-82-1 The information in the text is summarized as follows:

A siloxane oligomer bearing a chiral crown with high affinity for α-amino acids has been synthesized. The host is a modified form of a coronand first prepared by Cram, in which two 1,1′-binaphthol systems are linked through the oxygen atoms at the 2,2′-positions to form a 22-membered ring system containing six ether oxygen atoms attached to each other by four ethylene units. This was selectively mono-alkenylated to form an undec-10-en-1-yl derivative, which was bonded to linear siloxanes [HSiMe2O(SiMe2O)nSiMe2H] and [Me3SiO(Me2SiO)x(MeHSiO)ySiMe3] with total chain lengths of ca. 4 and 200 Si atoms resp., via a Pt catalyzed hydrosilylation reaction. The results came from multiple reactions, including the reaction of H-Phg-OEt.HCl(cas: 59410-82-1Product Details of 59410-82-1)
