Patent ID: 8785629

Claim:
A compound of formula (I) wherein R represents a group of formula (1) wherein R 1 represents H, a straight or branched (C 1 -C 6 ) alkyl group or a —(CH 2 ) m —R 2 group with R 2 selected from the group consisting of hydrogen, halogen, OH, N 3 , NH 2 , epoxy groups, leaving groups and carbonyl groups and m is an integer from 0 to 5, represents a double or a triple bond, p being equal to 0 when is a triple bond and equal to 1 when is a double bond or, R=R 2 with R 2 selected from the group consisting of hydrogen, halogen, OH, N 3 , NH 2 , epoxy groups and analogs, leaving groups, leaving groups involved into a transmetalation step catalyzed by Pd(0), and carbonyl groups, n is an integer from 0 to 5 X and Y independently of each other represent hydrogen, halogen or a straight or branched (C 1 -C 6 )alkyl group or an hydroxymethyl group, and R′ and R″ independently of each other represent a group selected from the group consisting of an oxymethylcarbonyl group of formula (2) wherein R 1 and R′ 1 are independently of each other hydrogen or (C 1 -C 4 )alkyl group and R′ 2 is a straight or branched (C 1 -C 6 )alkyl group or straight or branched (C 1 -C 6 )alkoxy group with the proviso that when R is cis-propenyl n=0 and R′2 is methyl, then R1 and R′1 are not simultaneously hydrogen, a thioethylcarbonyl group of formula (3) wherein R 3 is a straight or branched (C 1 -C 6 ) alkyl group a lipohilic chain selected from the group consisting of hexadecyloxypropyl (HDP)-, octadecyloxyethyl-, oleyloxypropyl-, and oleyloxyethyl-esters with the proviso that when n=0 then R is not the cis-propenyl or R′ and R″ form with the phosphate atom to which they are linked a cycloalkyle group of formula (4) wherein R 4 , R 5 , R 6 , and R 7 each independently represent a straight or branched (C 1 -C 6 )alkyl or aryl group or R 4 and R 7 independently represent a straight or branched (C 1 -C 6 ) alkyl or aryl group or R 5 and R 6 form together an aromatic ring, said aromatic ring being optionally substituted with the proviso that are excluded.
