The 3 S , 7 S and 3 S , 7 R stereoisomers of dianeackerone are to be drawn. Concept introduction: Stereoisomers are those compounds that differ in their stereochemistry around any one chiral carbon. They are designated as R , S , and the designation is based on the rotation of eye in moving from higher priority group (one which has higher molecular weight marked as 1 ) to lower ones (marked as 2 , 3 and 4 , with 4 having the lowest priority). If the eye rotation is clockwise, the designation is R , and if anticlockwise, the designation is S . Also, if the lowest priority group is above the plane, the designation is reversed.

Interpretation Introduction

Interpretation:

The 3S,7S and 3S,7R stereoisomers of dianeackerone are to be drawn.

Concept introduction:

Stereoisomers are those compounds that differ in their stereochemistry around any one chiral carbon. They are designated as R,S, and the designation is based on the rotation of eye in moving from higher priority group (one which has higher molecular weight marked as 1) to lower ones (marked as 2,3 and 4, with 4 having the lowest priority). If the eye rotation is clockwise, the designation is R, and if anticlockwise, the designation is S.

Also, if the lowest priority group is above the plane, the designation is reversed.

Brevicomin, the aggregation pheromone of the western pine bark beetle,contains a bicyclic bridged ring system and is prepared by the acidcatalyzedcyclization of 6,7-dihydroxy-nonan-2-one. Devise a synthesis of 6,7-dihydroxynonan-2-one from 6-bromohexan-2-one. You may also use three-carbon alcohols and any required organicor inorganic reagents

Several sulfonylureas, a class of compounds containing RSO2NHCONHR, are useful drugs as orally active replacements for injected insulin in patients with adult-onset diabetes. These drugs decrease blood glucose concentrations by stimulating b cells of the pancreas to release insulin and by increasing the sensitivity of insulin receptors in peripheral tissues to insulin stimulation. Tolbutamide is synthesized by the reaction of the sodium salt of p-toluenesulfonamide and ethyl N-butylcarbamate . Propose a mechanism for this step.

1. The ketone 2-heptanone has been identified as contributing to the odor of a number of dairy products, including condensed milk and cheddar cheese. Describe the synthesis of 2-heptanone from acetylene and any necessary organic and inorganic reagents. 2. Compound A has the molecular formula C14H25Br and was obtained by reaction of sodium acetylide (HC≡CNa) )with 1,12-dibromododecane. On treatment of compound A with sodium amide, it was converted to compound B (C14H24). Ozonolysis of compound B gave the diacid HO2C(CH2)12CO2H. Catalytic hydrogenation of compound B over Lindlar palladium gave compound C (C14H26), while hydrogenation over platinum gave compound D (C14H28). Sodium-ammonia reduction of compound B gave compound E (C14H26). Both C and E yielded O═CH(CH2)12CH═O on ozonolysis. Assign structures to compound A through E so as to be consistent with the observed transformations.
