The strain in the nine- and ten-membered 2-ynones is reflected in the bond angles at C3 and C2 for the global minimum conformations obtained by Monte Carlo MM3* conformational searches. MacroModel v5.5: Mohamadi, F.; Richards, N. G. J.; Guida, W. C.; Liskamp, R.; Lipton, M.; Caulfied, C.; Chang, G.; Hendrickson, T.; Still, W. C. J. Comput. Chem. 1990, 11, 440. These are respectively: for cyclonon-2-yn-1-one, 164 and 168°; for cyclodec-2-yn-1-one (1), 171 and 171°. The higher homologue, cycloundec-2-yn-1-one, is essentially angle-strain free with corresponding bond angles of 177°.
