From the aerial parts of Hypericum perforatum L. we have isolated phloroglucinol 1 (see the formula), a homologue of 2, the latter isolated previously from the same extract and identified by 2D NMR (DQF COSY, PS NOESY, TOCSY, HSQC and HMBC) [1].[...]...
The product 2 was prepared from menthyl phenylsulfonyl acetate in situ by the solid-liquid PTC conditions without solvent.[...]
6-S-Trityl-mercapto-hexan-1-ol is an important compound, because its O-b-cyanoethyl-N , N-diisopropyl phosphoramidite derivative is the most widely used building block for the synthesis of 5'-thiol modified oligonucleotides.[...]
Menthyl phenylsulfonyl acetate was prepared from methyl phenylsulfonyl acetate by solid-liquid PTC trans-esterification conditions without a solvent [1].[...]
The experimental procedure follows the general synthesis of arylalkynes reported by Sonogashira [1].[...]
The product 2 was prepared via a direct condensation under solid-liquid phase transfer catalysis (S.L.P.T.C.) [1] conditions.[...]
