Pentaerythritol, (1,1,1-trishydroxymethyl)methyl methane and ( 1, 1,1-trishydroxymethyl)nitro methane are converted into 2-aryl-5.5-bis(hydroxymethyl), 2-aryl-5-hydroxymethyl-5-methyl- or 2-aryl-5-hydroxymethyl-5-nitro-1,3-dioxanes and a range of derivatives. X-Ray and NMR analysis establishes that the latter is obtained as a single diastereomer whose structure is unambiguously determined. These materials can be elaborated to chiral derivatives of the starting (1.1.1-trishydroxymethyl) methanes. (C) 2002 Elsevier Science Ltd. All rights reserved.
