Short total syntheses of both the putative and actual structures of the clerodane diterpenoid (+/-)-sacacarin by double annulation.
Org. Lett. 3(25) , 4027-30, (2001) [reaction: see text] The putative structure of the naturally occurring clerodane diterpenoid (+/-)-sacacarin has been prepared in only 10 steps, six of which are C-C bond-forming steps, in a chemo-, regio-, and diastereoselective manner. The key part of the s... |

A heterocycle-forming double michael reaction. [5 + 1] annulation route to highly substituted and functionalized piperidines.
Org. Lett. 3(18) , 2911-4, (2001) [reaction: see text]. Nitrogen-containing tethered diacids, easily prepared by reductive alkylation of diethyl aminomalonate or ethyl cyanoglycinate, undergo double Michael reactions with 3-butyn-2-one to give highly functionalized and substituted piperidines... |

Chiral aminophosphines as catalysts for enantioselective double-Michael indoline syntheses.
Molecules 17(5) , 5626-50, (2012) The bisphosphine-catalyzed double-Michael addition of dinucleophiles to electron-deficient acetylenes is an efficient process for the synthesis of many nitrogen-containing heterocycles. Because the resulting heterocycles contain at least one stereogenic cente... |
