Wang, Yu-Hao published the artcilePhosphine-Catalyzed Annulations Based on [3+3] and [3+2] Trapping of Ketene Intermediates with Thioamides, Formula: C8H9NOS, the publication is Organic Letters (2021), 23(21), 8147-8152, database is CAplus and MEDLINE.
A novel annulation via ketene intermediates, allenyl imide I and alkynoates RC6H4CCC(O)OC6H4-4-NO2 (R = H, 4-MeC6H4, 2-ClC6H4, 3-BrC6H4, 4-FC6H4, 4-ClC6H4) bearing good leaving groups is used for their function in a tandem conjugate addition-elimination reaction (SN2′ type) promoted by nucleophilic phosphine catalysts and developed. By utilizing thioamides as R1C(S)NH2 (R1 = 4-chlorophenyl, thiophen-2-yl, naphthalen-2-yl, etc.) 1S,3N-bis-nucleophiles, [3+3] and [3+2] annulations have been established to allow rapid access to 1,3-thiazin-4-ones II and 5-alkenyl thiazolones III in high yields, resp. Furthermore, the possible reaction mechanisms are proposed on the basis of deuterium labeling experiments and d. functional theory calculations
