supporting information, p. 21723 - 21727 (2021/09/08)
An oxidative Pd-catalyzed intra-intermolecular dioxygenation of (aza-)alkenols has been reported, with total regioselectivity. To study the stereoselectivity, different chiral ligands as well as different hypervalent-iodine compounds have been compared. I

First enantioselective total synthesis of both (+)- and (-)-metachromin A
Brueggemann, Markus,Holst, Christiane,Hoppe, Dieter
, p. 647 - 654 (2007/10/03)
The antineoplastic agent (-)-metachromin A (1) from Hippospongia metachromia has been synthesized in enantiomerically pure form in 13% overall yield. A general convergent synthetic strategy for different metachromins using a 2-alkyloxy-3-sulfonyl-l,3-oxazolidine as a chiral dithienium equivalent is presented.
New isoxazolidine-based chiral auxiliaries for asymmetric syntheses
Abiko, Atsushi,Liu, Ji-Feng,Wang, Guo-Qiang,Masamune, Satoru
, p. 3261 - 3264 (2007/10/03)
New chiral auxiliaries based on the bicyclic-isoxazolidine skeleton, 3-oxa-2,7-diazabicylo[3,3,0]octane derivatives, were synthesized in 60-80% overall yields from amino acids. Asymmetric alkylation and boron aldol reaction using the auxiliaries proceeded with high selectivities. 'Carboxylic amide' has been used for the asymmetric boron-mediated aldol reaction for the first time.
Diastereoselective formation of 2-aryl-3-arenesulfonyl 4-ethyl-1,3-oxazolidines: An X-ray crystallographic and 1H NMR study

, p. 3391 - 3396 (2007/10/03)
N-Arylsulfonamides of (R)- and (S)-2-amino-1-butanol, on condensation with aromatic aldehydes produced diastereomerically pure 2-aryl-3-arenesulfonyl 4-ethyl-1,3-oxazolidines. The absolute configurations of one enantiomeric pair have been determined from
