Abstract
Highly regio- and stereoselective synthesis of dispiropyrrolo[2,1-a]isoquinoline-oxindoles have been developed by the one-pot three component reaction of isatins, 1,2,3,4-tetrahydroisoquinoline (THIQ), and a thiazolo[3,2-a]indole derivative. The reaction proceeds regioselectively through an exo-Re face approach of the in situ generated tetrahydroisoquinolium ylides towards the dipolarophile yielding the corresponding [3+2] cycloadducts in excellent yields and stereoselectivity.

- 29 The cycloaddition of substrates (i) 3b in EtOH, (ii) 3c in PrOH, and (iii) 3d in i-PrOH resulted in the formation of compounds 6n, 6o, and 6p, respectively. In the case of 6n and 6o, transesterification took place for ester group attached to pyrrolidine ring while this was not observed during the formation of 6p.
