Abstract:: Enantioselective epoxidation of crotyl alcohol, followed by a cuprate mediated methylation, gave a 1:1 mixture of (2S) -3- methyl -1,2- butanediol and (2R,3S)-2-methy1-1,3- butanediol. The latter was separated as its 2,4,6-trimethylbenzenesulfonate derivative and converted via the iodide to the corresponding phosphonium salt. The separated butanediol derivatives were independently transformed to...

Abstract:: Bromoalkoxylation of dihydropyran with bromine and 1-borneol, followed by dehydrobromination and epoxidation, afforded trans-2-1- bornyloxy-3,4-epoxytetrahydropyran as a major product. This was treated with sodium phenylselenide to give a 1:1 mixture of (2R,3R,4R)- 2-1-bornyloxy-3-hydroxy-4-phenylselenotetrahydropyran and its (2S,3S, 4S) diastereomer. Elimination of the selenoxide, derived from oxidation of the former with hydrogen...

Abstract:: Several approaches to the synthesis of penicillin from 2-iminothioazolidine 50, from 2-thiothiazolidine 66 and by photocyclization of 77 and 78 were investigated. 2-Iminothiazolidine 50 was prepared from dibromoester 45 by the action of benzylamine followed by treatment of aziridine 46 with potassium or ammonium thiocyanate. Attempted introduction of a two-carbon...
