THALLIUM NITRATE AS A REAGENT FOR THE CONVERSION OF EPOXIDES INTO α-HIDROXY-NITRATE ESTERS AND FOR THE CLEAVAGE OF ALIPHATIC ETHERS

Simple as well as steroidal oxiranes are converted into the corresponding α-hidroxy nitrate esters by treatment with Tl(NO3)3 in hexane solution.Moreover aliphatic ethers react with Tl(NO3)3 in acetic anhydride via cleavage of the ethereal bond and formation of the corresponding acetoxy derivatives.

We prepared the geometric isomers of decahydro-2-naphthols as the source materials for the synthesis of poly(decahydro-2-naphthyl methacrylate)s [poly(DNMA)-I, -II, -III, and -IV] including alicyclic ester groups with different geometric structures. The geometry and conformational dynamics of the decahydro-2-naphthyl moieties were investigated by NMR spectroscopy and DFT calculations. We synthesized each isomer of the methacrylic monomers, polymerized them, and investigated the optical, thermal, and mechanical properties of poly(DNMA)s with different isomer compositions. The Tg values of the poly(DNMA)s were in the following order: 139.3 C for poly(DNMA)-II 3/g, 1.489, and 42-44, respectively.

The oxidation of trans-decahydronaphthalene (1) was carried out in acetic anhydride with oxygen in the presence of Co(OAc)2, Ce(OAc)3, and NH4Br.Decahydronaphthyl acetates were obtained as main oxidation products in a selectivity of 81 molpercent at 120 degC.In addition, relative reactivities of hydrogen atoms of 1 were determined at temperatures from 90 to 120 degC.

Asymmetric hydrolysis of chloroacetates of (+/-)-axial-alcohols (+/-)-neomenthol (2), (1RS,4aRS,8aSR)-decahydro-1-naphthol (6) by Trichoderma koningi gave (-)-(1S,3R,4R)-neomenthol (2) (54percent optical purity, o.p.) and (-)-(1R,4aR,8aS)-decahydro-1-naphthol (6) (66percent o.p.) with their enantiomeric chloroacetates.However, the chloroacetate of (2RS,4aRS,8aSR)-decahydro-2-naphthol (10) was hydrolyzed by T. koningi to give the (-)-alcohol (10) (12percent o.p.) with low enantioselectivity.
