Abstract
Regioselectivity of Ln(OTf)3-catalysed alcoholysis of 2,3- and 3,4-epoxy alcohols was closely investigated to expand the scope of the transformations. The synthetic use was demonstrated by application to the construction of 4-propoxy-5-hydroxy-2,3-pentanedione (C4-propoxy-HPD), which is a potent synthetic mediator in AI-2 quorum sensing.

Abstract
A practical and convenient method for the efficient and regio- and stereoselective ring-opening of enantiopure monosubstituted epoxides by sodium azide under hydrolytic conditions is reported. The ring-opening of enantiopure styryl and pyridyl (S)-epoxides by N3- in hot water takes place preferentially at the internal position with complete inversion of configuration to produce (R)-2-azido ethanols with up to 99% enantio- and regioselectivity, while the (S)-adamantyl oxirane provides mainly the (S)-1-adamantyl-2-azido ethanol in excellent yield. In general, 1,2-amino ethanols were obtained in high yield and excellent enantiopurity by the reduction of the chiral 1,2-azido ethanols with PPh3 in water/THF, and then converted into the Boc or acetamide derivatives.

Abstract
![]()
The
first catalytic, highly C3-selective, stereosepecific ring-opening
reaction of 2,3-epoxy alcohols and 2,3-epoxy sulfonamides has been
accomplished. This process was efficiently promoted by W-salts, and
the developed method was applicable to various epoxides with diverse
N- and O-nucleophiles affording the products in good to excellent
yields (up to 95%) and generally with high regioselectivities (C3:C2
up to >99:1).
