Ej. Corey et al., CATALYTIC ENANTIOSELECTIVE DIELS-ALDER REACTIONS USING TITANIUM COMPLEXES OF CIS-N-SULFONYL-2-AMINO-1-INDANOLS, Tetrahedron letters, 34(52), 1993, pp. 8399-8402
A titanium complex derived from (1R, (2,4,6-trimethylbenzenesulfonyl)-
2-amino-1-indanol catalyzes the Diels-Alder reaction of 2-bromoacrolei
n and cyclopentadiene with 96.5:3.5 enantioselectivity. A new and effi
cient synthesis of 2-amino-1-indanol (6) contributes to the potential
of this methodology.
