  Convenient Synthesis of 4-C-Branched Lactones and 3′-C-Branched 2′,3′-Dideoxynucleosides

  摘要：

  The regio- and stereoselective photocatalysed addition of 2-propanol and cyclopentanol to (5S)-hydroxymethylfuran-2(5H)-one (1) gave 4-C-branched lactones 2 and 3 after selective silylations. The lactones 2 and 3 were radically deoxygenated affording lactones 4 and 5, respectively. As an example, compound 2 was transformed without purification of the intermediates into an anomeric mixtures of deprotected 3'-C-branched 2',3'-dideoxynucleosides 6 by the following reaction sequence: silylation, reduction, acetylation, coupling with silylated thymine and desilylation.
