, p. 6579 - 6585 (1998)
Exploiting 1,3-dipolar cycloaddition and carbanilide cyclization transformations, we have prepared novel spirocyclic isoxazoloimidazolidinedione heterocycles of generalized structures II and III on solid phase starting from Merrifield resin. Cyclopentanoid isoxazoloimidazolidinedione II was obtained with complete diastereoselectivity, and cyclopropanoid isoxazoloimidazolidinedione III was obtained as an ≈ 2:1 mixture of diastereomers.
Complete facial selectivity in the Diels-Alder reaction of a 5-amino-5-carboxycyclopentadiene derivative

5-tert-Butoxycarbonylamino-5-carbethoxy-2-tert-butyldimethylsilyloxy- cyclopentadiene undergoes a Diels-Alder reaction exclusively from the face syn to the nitrogen functionality. Complete reversal of facial bias may be achieved, but at the cost of dimini
Regio- and diastereoselective synthesis of cyclic amino esters
Park, Kyung-Ho,Kurth, Thomas M.,Olmstead, Marilyn M.,Kurth, Mark J.
, p. 991 - 992 (2007/10/03)
Several cyclic amino esters have been prepared regio- and diastereoselectively depending on the electrophile (cis or trans alkene) and its leaving group.
