of oligo-1,4-diol building blocks has been realized via (a) propargylation of an aldehyde with allenylzinc bromide, (b) alcohol protection and (c) ruthenium-catalyzed anti-Markovnikov hydration of the terminal alkyne to release an aldehyde for the next iteration. Linear chains with 1,4-, 1,4,7- 1,4,7,10- and 1,4,7,10,13- functionalization patterns have been obtained by consecutive sequential iterations
