The fully regioselective reactivity of four new highly substituted silyl aryl triflate aryne precursors in aryne acyl-alkylation, acyl-alkylation/condensation, and heteroannulation reactions is reported. The application of these more complex arynes provides access to diverse natural product scaffolds and obviates late-stage functionalization of aromatic rings.

The present invention relates to a compound of formula (I) wherein: - i is 0 or 1; j is 0 or 1; k is 0 or 1; - R1 and R2 are in particular H, (C1-C12)alkyl, or a group of formula C(O)R; - R is a, linear or branched, alkyl radical, comprising at least 19 carbon atoms; - R3 is H and k=0 when j=1; or, when j=0, R3 is -C(O)R or -L-C(O)R; - L, U and L" are linkers; wherein, when j=0, at least one of the groups R1; R2 and R3 comprises a radical R.
