| abstract | The procedure for the preparation of the compound of formula (II) where Pg is selected from the group consisting of benzyl, substituted benzyl, -CH2OCH3, -CH2SCH3, -OCH2OCH2Phenyl, -CH2OCH2CH2OCH3, -CH2OCH2CCl3, -CH (OCH2CH2Cl) 2, CH2OCH2CH2 ) 3, -CH (OC2H5) CH3, -C (OCH3) (CH3) 2, -CH (CH3) OCH (CH3) 2, -CH2CCl3, -C (CH3) 3, -CH2CH = CH2, -CH2CH = CHphenyl , -CH (phenyl) 2, -C (phenyl) 3, tetrahydropyranyl, 4-methoxytetrahydropyranyl, 3-bromotetrahydropyranyl, tetrahydrothiopyranyl, 4-methoxytetrahydrothiopyranyl, tetrahydrofuranyl, tetrahydrothiofuranyl, and SiR1R2R3, each being R1, R2 and R2. C4, phenyl, benzyl, substituted phenyl or substituted benzyl, from a 4-0-protected cyclopentenone, said cyclopentenone dissolves in an organic solvent and the solution is treated with a Lewis acid and a reducer at a temperature between -100 ° C and 20 ° C. Procedures are also described for obtaining the enantiomers of said compound of formula (II) from the corresponding enantiomer of cyclopentenone, and procedures for obtaining said enantiomers of the compound of formula (II) and enantiomers of cis-4-0- esters. Protected-2-pentenyls from a racemic mixture of cyclopentenone by means of a suitable acylating agent. |
