Kumar, Amit,Panda, Gautam
supporting information, (2021/04/09)
We herein report Magnesium chloride (MgCl2) catalyzed first highly C3-selective ring-opening reaction of various 2,3-epoxy alcohols with assorted N-Nucleophiles and sodium azide to furnish 3-amino-1,2 diols and 3-azido-1,2 diols respectively in high yields under mild reaction conditions. This protocol attributes the use of catalytic amount of Magnesium chloride (MgCl2), simple reaction conditions, practical operation and broad functional group tolerance.

The synthesis of three new analogues of the cyclic cationic antimicrobial peptide Gramicidin S is described. These derivatives contain a modified turn region in which the DPhe-Pro motif has been replaced by a constrained furanoid sugar amino ac
The efficient resolution of protected diols and hydroxy aldehydes by lipases: Steric auxilliary approach and synthetic applications
Kim,Lim,Choi,Whang,Ku,Choi
, p. 71 - 76 (2007/10/03)
1,n-Diols (n = 2-5) and 2-hydroxy aldehydes protected with a steric auxilliary are transformed by Pseudomonas lipases with high enantioselectivity, thus allowing the efficient resolution of these molecules and the synthesis of related derivatives with high optical purity.
Ring-opening of glycidyl derivatives by silanes mediated by Ti(O-i-Pr)4 or Al(O-i-Pr)3: Access to versatile C3 building blocks
Sutowardoyo,Sinou
, p. 437 - 444 (2007/12/18)
Ring-opening of chiral glycidol or glycidyl tosylate by Me3SiN3 or Me3SiCN catalyzed by Ti(O-i-Pr)4 or Al(O-i-Pr)3 occurred in a regiospecific manner and with very high stereoselectivity, leading to new trifunctionalized chiral building blocks. The enantiomeric excess of the ring-opened products was 90-95%, as determined by 1H NMR of the Mosher ester derivatives, indicating that there was no significant loss of optical purity during the ring-opening. This methodology was applied for the one-pot synthesis of (R)-1-azido-3-naphthyloxy-2-hydroxypropane in 94% ee, a precursor of analogs of propranolol.
