Abstract
A thio-Michael–aldol–cyclization cascade reaction of N-enoyl thiazolidinethiones with aliphatic aldehydes and cyclic ketones was promoted by Ti(IV) chloride to deliver highly complex tricyclic adducts possessing a carbon atom tetrasubstituted with heteroatoms and up to four stereogenic centers in good to very good yields.
