Md. Groaning et al., Allyldimethyltritylsilane: construction of enantiomerically pure cyclobutano[c]fused pyrrolidines, TETRAHEDRON, 57(13), 2001, pp. 2635-2642
Cyclobutannulation of the bicyclic lactam with allyldimethyltritylsilane is
accomplished in high yield with good diastereoselectivity. The resulting t
ricyclic system is converted to a enantiomerically pure cyclobutane-fused p
yrrolidine. (C) 2001 Elsevier Science Ltd. All rights reserved.
