Recently, in their study of molybdenum-mediated allenic Pauson-Khand reaction, Cook and co-workers observed the formation of distal adducts in 30-40% yield, by heating of conformationally restricted diyne-allenes in toluene at 100°C in the absence of any catalyst. As far as we are aware, this is the first example of thermal [2 + 2] cycloaddition between unactivated allenes and alkynes, see: (a) Cao, H.; Flippen-Anderson, J.; Cook, J. M. J. Am. Chem. Soc. 2003, 125, 3230-3231.

However, these result does not conflict with the biradical mechanism depicted in Schemes 14 and 15, because intramolecular coupling or biradicals such as 94 and 101 to the corresponding cyclobutanes would be extremely fast.

In order to determine the relative configuration between C-4 and C-1 (or C-4 and C-8), transformation of 11a and 67 to the corresponding saturated analogues 68 and 69 was desirable. We could unambiguously confirm the relative configuration of 68 and 69 by NOEs including that of the introduced hydrogens at C-5 and C-6. For more details, see the Supporting Information
