Total synthesis of (R)-(−)-actisonitrile via O-alkylation of optically active 4-hydroxymethyloxazolidin-2-one derivative
摘要:
The enantioselective synthesis of (R)-(-)-actisonitrile 1 has been achieved via O-alkylation of (4R,alpha S)-4-hydroxymethyl-3-(alpha-methylbenzyl)oxazolidin-2-one (alpha S)-4 with 1-iodohexadecane in the presence of CsOH in DMF. Under these reaction conditions, the O-alkylation was much faster than the intramolecular acyl transfer of (alpha S)-4. (C)2011 Elsevier Ltd. All rights reserved.

The syntheses of N-substituted 1-O-alkyl-2-desoxy-2-amino-sn-glycero-3-[32P]phosphocholines were performed in four steps starting from [32P] POCl3 and the corresponding 1-O-alkyl-2-amino-propane-3-ols in 5-7% total yield.

The synthesis of two types of enantiomerically pure sn-2-deoxy-2-amido-glycero-phospholipids differing in the connection of the alkyl chain at the sn-1-position is described. Both types of lipids were prepared from L-serine-methylester as the chiral starting material. (C) 2000 Published by Elsevier Science Ireland Ltd.

A series of 1-ether-sn-2-acylamidoglycerophospholipids, bearing different polar heads in sn-3-position such as phosphoglycol, -serine, -ethanolamine or -choline, have been prepared. Except for the choline derivative which was synthesized from a beta-carbamate alcohol derivative, the remaining compounds were obtained from beta-amidoalcohols.
