Abstract
Reaction of dialkyl acetylenedicarboxylates 1a-c andpyrrole derivatives 2a-e in the presence of triphenylphosphite (TPP) was investigated and the effect of the pyrrole substitution was established. Diastereoselectivity is observed with pyrroles, 2a,b, yieldingphosphonate ester derivatives 3a-f and 4,and their relative configuration is determined by 1H/13C and 31P NMR and confirmed by single X-ray diffraction. Similar reactions with higher degree of substitution of the pyrrole, 2c,e showed no diastereoselectivity.
