Abstract

ROBLES-MARIN, Elvis; A. SANCHEZ, César  and  URBINA-GONZALEZ, Juan-Manuel. A mild procedure for the synthesis of allyl and benzyl α-hydroxyesters using 0-allyl (benzyl)-N,N’- dicyclohexylisourea. Rev. Soc. Quím. Perú [online]. 2017, vol.83, n.2, pp.143-159. ISSN 1810-634X.

Allyl protecting group and more commonly used benzyl protecting group were easily introduced in several (cyclo)alkyl α-hydroxycarboxylic acids through a modified Steglich esterification using O-allyl or O-benzyl-N,N’-dicyclohexylisoureas. Corresponding esters were prepared under mild conditions and short reaction times; high reaction yields and easy purification of final products favored this procedure. Complete unambiguous assignment for ¹H and ¹³C-NMR data for prepared compounds is given

Keywords : Dicyclohexylcarbodiimide; O-allylisourea; α-hydroxyallylester; O-benzylisourea; α hydroxybenzylester.
