  Cyclodiphosph(III)azane chemistry – Ylides from the reaction of [(RNH)P-N(t-Bu)]2 [R=t-Bu, i-Pr] with dimethyl maleate and chiral ansa-type derivatives from reaction of [ClP-N(t-Bu)]2 with a substituted BINOL

  摘要：

  Use of a simple inorganic ring system with the cyclodiphosph(III) azane skeleton [e.g. [(RNH)P-N(t-Bu)](2) [R = t-Bu (7), i-Pr (8)] to probe some of the intermediates proposed in phosphine mediated organic reactions is highlighted. Thus the reaction of 7-8 with the allenylphosphine oxide Ph2P(O)C(Ph)=C=CH2 (9) affords the phosphinimines [(RNH)P(mu-N-t-Bu)(2)P(=N-R)-C(=CH2) CH(Ph)-P(O)Ph-2] [R= t-Bu (10), i-Pr (11)], while a similar reaction of 7-8 with dimethyl maleate (or dimethyl fumarate) affords the ylides [(RNH) P(mu-N-t-Bu)(2)P(NH-R)=C(CO2Me)-CH2(CO2Me) [R = t-Bu (18), i-Pr (19)]. The implication of such reactions on phosphine mediated organic transformations including Morita-Baylis-Hillman reaction is mentioned. In a rather rare type of situation, an unusually long phosphoryl (P=O) bond [1.538 (5) angstrom] as revealed the X-ray structure of {(R)-6,6'-(t-Bu)(2)-1,1'-(C10H5)(2)-2,2'-O-2-}{P(O)(N-t-Bu)(2)-P(Se)} (27) is rationalized by means of crystallographic disorder in packing after comparing the data with that in the literature and {1,1'-(C10H6)(2)-2,2'-O-2}{P(Se)(N-t-Bu)(2)-P(Se)} (29). X-ray structures of the new compounds 10-11, 18-19, 27 and 29 are discussed. Compound 10 crystallizes in the chiral space group Pca2(1) with (S)-chirality at the carbon center [-C(=CH2) CH(Ph)-P] suggesting a case of spontaneous resolution through crystallization.

  Phosphano-indoles were synthesized in a fairly straightforward route from the reaction of simple cyclodiphosphazanes [XP(μ-N-t-Bu)2PY] [X = Y = NH-t-Bu (1a); X = Y = NH-i-Pr (1b)] with o-aminophenyl functionalized propargyl alcohols. The reaction occurs via an allene intermediate formed by P III-O-C → P V(O)-C rearrangement, followed by cyclization utilizing the central allenic carbon and the –NH2

  The apparently simple reaction of the P(III) precursors [(RNH)P(μ-N-t-Bu)2PY] (Y=NH-t-Bu, Cl), (OCH2CMe2CH2O)PCl, and Ph2PCl with functionalized propargyl alcohols is examined. In most cases, the final products are not the expected allenes but several previously unpredicted structural motifs, such as substituted oxazabenzocycloheptenones, indolinones, and fused heterocycles as revealed by X-ray crystallography
