2-Metalloalkylbenzothiazoles 2, readily available from 2-alkylbenzothiazoles 1, undergo aldol reaction to give aldols 3 and 4.Low to satisfactory threo diastereoselection was observed with 2-lithio- and 2-trimethylsilyl derivatives 2b-d and 2e-g.High to e

Photolytic, thermal, and acid-catalyzed -eliminations of methanethiol from the benzobicyclic β-lactone dithioaqcetal 1 to form the benzothiazole derivatives 4 and 5 are investigated.Competing reactions are -substitutions, which ultimately yield 2-benzylbenzothiazole (6) and benzaldehyde.Intermediate 7 is isolated upon careful hydrolysis.These reactions are compared to -eliminations from the 1,5-benzothiazepine 9 and to its -rearrangement to give 10. 9 and 10 are not intermediates in the reactions of 1.The stereochemistry of 7 and 10 is discussed.
