Abstract

(TLC). Similarly, decomposition of 14a in Me2S0 also gave 15a in 28% yield (Scheme 111). The structures of 15a and 15b were confirmed by comparison with authentic materials6 (mixture melting point, TLC, NMR). The isolation of 151% and 15b in the cyclizations of n- butyl trithiocarbonates 14a and 14b led us to reexamine the cyclization of the tert-butyl trithiocarbonate lla in
