一般說明

Ethyl 1,3-dithiolane-2-carboxylate is an α-keto acid equivalent. It participates in the conjugate additions to enones.[1][2] It is a bulky equivalent of acetate undergoing syn-selective aldol reactions.[3] Anion derived from ethyl 1,3-dithiolane-2-carboxylate participates as nucleophile during the total synthesis of the corynanthe alkaloid dihydrocorynantheol and the formal syntheses of the indole alkaloids tacamonine, rhynchophylline and hirsutine.[4] It also participates in the conjugate addition of enolates to phenylglycinol-derived α,β-unsaturated δ-lactams.[5]

其他說明

α-酮酸等价物;对烯酮的共轭加成[1][2];进行顺式选择性羟醛反应的乙酸酯大位阻等价物[3]
