✦ Synopsis

Addition oP C,F'-dialkylphosphorodithioic acids to fully protected 1,2-unsaturated hsxo-and pentopyranoses gives S-(2-deoxy-glycosyl)-phosphorodithioates 'P -OH RO' 'SH -# H /OR HS-l'OR 2 2 Scheme I 2oa the &_-adducte. The observed Oc'/s ratio was 89:ll and 92:8, respectively. pllso in these cases isolation oP the &-isomers 3f and 3 was readily accomplished by crystallization.
