A method for preparing a compound of formula (I)
in which
R1 is selected from H and alkyls,
R2 is selected from H, alkyls, OR′ where R′ is selected from alkyls, silyls, CO-alkyl,
R3 is selected from the acyl groups of the CO(R″) type, and the CO(OR″), CO(NR″R′″), PO(OR″)(OR′″), PO(OR″)(R′″) groups where R″ and R′″, independently of each other, are selected from H and alkyls,
R represents a C(R4)═C(R5)(R6) group where R4, R5 and R6, independently of each other, are selected from H, linear or cyclic alkyls and alkenyls, aryls, alkylaryls, or R4 and R5 together form a saturated or unsaturated, substituted or unsubstituted ring,
from a compound of formula (II)
or a compound of formula (ill)
in which, R, R1, R2 and R3 have the above definition.
