Erythro and threo-1, 2-diphenyl-2-tert-butylsulfinylethanols 5 and 8 were prepared from the condensation of the α-lithio derivative of benzyl-tert-butyl sulfoxide with benzaldehyde. Reaction of 5 with sulfuryl chloride gave the title compound,(2 R*, 3 S*, 4 R*, 6 R*)-3, 4- diphenyl-6-(diphenylmethyl)-1, 5-dioxa-2-thiane-2-oxide 6, the first representative of a new heterocyclic ring system. Similar treatment of 8 resulted in the formation of 7, a ...
