TL;DR: This tutorial review will describe Lewis base-promoted annulation reactions with MBHADs, with a special emphasis on recent work regarding diverse reactivities of MBH ADs.

TL;DR: The Rauhut-Currier reaction has proved itself as a promising strategy for synthesis of multifunctionalized molecules, although still being in its infancy with regard to limitations of selectivity and scope.

TL;DR: A novel phosphine-catalyzed domino reaction of salicyl N-thiophosphinyl imines and allylic carbonates was developed, offering a powerful approach to the construction of a highly substituted trans-2,3-dihydrobenzofuran skeleton with high diastereoselectivity.

TL;DR: The first phosphine-catalyzed [4 + 2] annulation of γ-substituted allenoates with 2-arylidene-1H-indenes-1,3(2H)-diones is disclosed, offering a powerful approach to the construction of highly substituted spiro[4.5]dec-6-ene skeletons in excellent yields, and with complete regioselectivity and high diastereoselectivities.

TL;DR: A novel domino reaction catalyzed by triphenylphosphine was developed for synthesis of the highly functionalized chroman derivatives and the first example that the gamma-CH(3) of allenoate undergoes cyclization to form chroman derivates was reported.
