Addition of 1-lithio-1-phenylthiopropa-1,2-diene (7) to ketones, followed by trifluoroacetylation, a 3,3-rearrangement, and methanolysis of the resulting dienol trifluoroacetates, leads to the C-3 homologated α-phenylthioenones (2a) in 31–66% overall yields.
在酮中添加1-lithio-1-phenylthiopropa-1,2-diene(7),然后进行三氟乙酰化,3,3-重排和甲醇化生成的二烯醇三氟乙酸酯,导致C-3均化α-苯基硫代烯酮(2a)占总产量的31–66%。
