    Carbanion-accelerated Claisen rearrangements. 8. Phosphonamide anion-stabilizing groups
    摘要:
    The utility of various phosphonamide groups has been examined in the context of the carbanion-accelerated Claisen rearrangement (CACR). An extensive survey has identified the N,N'-dibenzyl-1,3,2-diazaphospholidine group 11 to be optimal in the ease of construction of the CACR precursors and the facility and stereoselectivity of the rearrangement. Using n-butyllithium as the base, the phosphonamides rearranged readily at -20-degrees-C with complete regioselectivity and in good yield (74-79%). The phosphonates also showed a high level of diastereoselectivity (> 95% de) but the yield from the (Z)-2-butenyl precursor (anti product) was only 45%. A chiral N,N'-dibenzyl-1,3,2-diazaphospholidine 12 derived from trans-1,2-cyclohexanediamine was examined. Although the CACR proceeded very cleanly (71-85%) and with high internal selectivity (94% de), the relative asymmetric induction was poor (16-20% de). This was also the case for a chiral N,N'-dibenzyl-1,3,2-diazaphosphorinane 15 derived from (R,R)-1,3-diphenyl-1,3-propanediamine and N,N'-dibenzyl-1,3,2-diazaphosphepine 16 derived from 6,6'-dimethyl-2,2'-diaminobiphenyl. The characteristic features of the CACR were compared with the aryl sulfone and phosphonate versions.

    derivatives (3e–3h) were pre‐ pared. Followed by hydrolysis, the reaction of 3a–3c with PCl3 successfully led to the formation of cor‐ responding metastable saturated heteroatom‐substituted secondary phosphine oxides (HASPO 4a–4c), a tautomer of the saturated heteroatom‐substituted phosphinous acid (HAPA). Whereas ambient‐stable diamine‐coordinated palladium complexes were obtained, HAPA‐coordinated palladium

  • Crystal structure of a hybrid salt–cocrystal and its resolution by preferential crystallization: ((±)trans-N,N′-dibenzyldiaminocyclohexane)(2,3-dichlorophenylacetic acid)<sub>4</sub>

    trans-N,N′-Dibenzyldiaminocyclohexane (B) crystallizes with 2,3-dichlorophenylacetic acid (AH); the crystal structure, resolved by using crystal X-ray diffraction, revealed an odd stoichiometry composed of H2B2+, two A− and two AH forming an unexpected hybrid salt–cocrystal. As this compound is a stable conglomerate (i.e. every single crystal contains the enantiomerically pure cation H2B2+, RR or SS), several preferential crystallization attempts (AS3PC) were performed in methanol and in THF and gave unexpected final enantiomeric excesses greater than 20% for the entrainment in methanol. These results suggest that the crystal growth mechanism preferentially involves building units composed of [H2B2+; 2A− and 2AH] or reconstruction of some crystal interfaces rather than a layer by layer construction.
    反式-N,Nâ²-二苄基二环己烷(B)与 2,3-二氯苯乙酸(AH)结晶;通过晶体 X 射线衍射法解析的晶体结构显示,H2B2+、两个 Aâ 和两个 AH 组成的奇特配比形成了意想不到的混合盐结晶。由于这种化合物是一种稳定的团聚体(即每个单晶体都含有对映体纯阳离子 H2B2+、RR 或 SS),因此在甲醇四氢呋喃中进行了几次优先结晶尝试(AS3PC),结果发现在甲醇中夹杂的最终对映体过量率出乎意料地超过了 20%。这些结果表明,晶体生长机制优先涉及由 [H2B2+; 2Aâ 和 2AH] 组成的构建单元或某些晶体界面的重建,而不是逐层构建。
