The heptapropionates 5 and 20 were synthesised by iterative applicatio
n of the boron-mediated aldol reaction of ethyl ketone (R)-4 and subse
quent reduction. Polyketide library diversification was realised by va
rying the ketone configuration and substitution in the aldol bond cons
tructions. (C) 1997 Elsevier Science Ltd.
