Convenient synthesis of 4-C-branched lactones and 3'-C-branched 2',3'- dideoxynucleosides
Wengel, Jesper,stergaard, Kirsten,Hager, Anders
, p. 1361 - 1368 (1996)
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 lact
