β¦ Synopsis
A total convergent synthesis of lipoxins A4 and B4 has been carried out via four optically pure a-hydroxy and a$-dihydroxyaldehydes, obtained from D-isoascorbic acid as a single starting material.
Connection by a six carbons unit uses Wittig-type reactions notably involving a stabilized arsonium ylide.
We have previously reported a general method for the preparation of enantiometically pure a-hydroxy

A convenient synthesis of (S)-and (R)-4-vinyl oxazolidin-2-one 1 and 2 from the same inexpensive starting material, D-isoascorbic acid, is described. The title compounds were obtained in 44% and 38% yield, respectively, by operationally simple steps. This approach is a suitable alternative to the li
Ascorbic and D-isoascorbic acids were employed in syntheses of 9-(2 0 ,3 0 ,4 0 -trihydroxybutyl)adenines protected at 3 0 and 4 0 oxygens (all four enantiomers) and at 2 0 oxygen (2 0 S,3 0 R and 2 0 S,3 0 S enantiomers).
