Write the formula for each of the following compounds (a) hydrogen iodide, (b) calcium chloride, (c) lithium oxide, (d) silver nitrate, (e) iron(II) sulfide, (/) aluminum chloride, (g) ammonium sulfate, (h) zinc carbonate, (/) iron(lll) oxide, ( ) sodium phosphate, (k) iron(H) acetate, (/) ammonium cyanide, and (m) copper(II) chloride. 

In view of the multicomponent nature of the tandem [4 + 2] / [3 + 2] cycloaddition, the potential for a combinatorial approach to the synthesis of nitroso acetals has been investigated on solid-phase supports. The incorporation of either the dipolarophile or the starting nitroalkene on a Wang-type resin is compatible with the tandem cycloaddition promoted at high pressures (Schemes 2.28 and 2.29). The solid-supported nitroso acetals are subsequently liberated (in moderate yields from the staring nitroalkene) upon the addition of a catalytic amount of potassium cyanide in triethylamine and methanol or by reduction with lithium aluminum hydride (LAH) (261,264). 

The radiolabel was introduced by displacement of a quaternary amine with potassium 14C-cyanide to give a nitrile. The nitrile was readily converted to indole-3-acetic acid by hydrolysis with 20% aqueous potassium hydroxide. Reduction of the indole-3-acetic acid derivative with lithium aluminum hydride in tetrahydrofuran gave a typtophol with 95% yield. 

For the synthesis of 13-hydroxysparteine the starting material was a-picoline iV-oxide (CXVIII) which was nitrated and the nitro group then replaced by benzyloxy. The action of acetic anhydride induced the Boekelheide rearrangement to the acetoxymethyl derivative CXIX. The latter, via the alcohol, the chloride, the cyanide, and the ester, was condensed with ethyl hydroxymethylenepyridylacetate to the quinol-izone CXX, hydrogenation and reduction of which with lithium aluminum hydride gave a separable mixture of hydroxysparteines.

Toward this end, a Fischer indole synthesis employing 4-carbethoxycyclo-hexanone (212) and phenyl hydrazine in warm acetic acid was followed by reduction of the resulting indole with lithium aluminum hydride to fomish hydroxymethyltetrahydrocarbazole 213. Alcohol activation with tosyl chloride and subsequent displacement of the tosylate with cyanide yielded nitrile 214. Oxidation with periodic add in methanol then formed ketone 215. Reduction of both the nitrile and carbonyl moieties was next achieved using lithium aluminum hydride in a mixture of THF and glyme at reflux to furnish aminoalcohol 216. A thermal dehydrative cyclization via heating this product in o-dichlorobenzene at reflux then led to 1,3-(iminoethano)carbazole 83.

Disulfides can be easily reduced to corresponding mercaptans—for example, with alkali cyanide or with zinc and sulfuric acid in acetic acid, or also with lithium aluminum hydride—and the mercaptans can then be easily detected or identified by known procedures (p. 386).
