Process for preparing indane-like compounds

A compound of the Formula III′

• R1 is selected from the group consisting of hydrogen, —OR4, —SR5, C1-C3 alkyl, C2-C3 alkenyl, halo, —CN, —COR4b′, and —OC(O)—R15;
• m2 is from 0 to 2;
• R4 is hydrogen, C1-C3 alkyl;
• R5 is hydrogen, C1-C3 alkyl;
• R10 is selected from the group consisting of hydrogen, carbonyl, halo, and C1-C3 alkyl;
• R11 is selected from the group consisting of hydrogen and C1-C3 alkyl;
• R12 is independently selected from the group consisting of hydrogen, C1-C10 alkyl, and aryl;
• R13 is independently selected from the group consisting of hydrogen, C1-C10 alkyl, and aryl;
• or
• R12 and R13 together with the nitrogen to which they are attached form a group of the formula II:
• II′ wherein the II′ group is a group of Formula II which is unsaturated;
• or
• R11 and R12 together with the nitrogen and carbon to which they are bound can join to form a three to six membered ring;

• R17 is independently selected from the group consisting of hydrogen, —OR4′, —SR5′, C1-C3 alkyl, C2-C3 alkenyl, halo, —CN, S(O)m2′, —COR4b, and —OC(O)—R15;
• R4b and R4b′ are each independently selected from hydrogen and C1-C3 alkyl;
• R15′ is C1-C3 alkyl or aryl;
• m2′ is 0 to 2;
• R4′ is hydrogen, C1-C3 alkyl;
• R5′ is hydrogen, C1-C3 alkyl;
• m2 is 0 to 2;
• X is selected from the group consisting of C, O, S, N, carbonyl, and a bond;
• n′ is 0 to 2;
• m′ is 0 to 2;
• m3 is 0 to 2;
• n is 0 to 3;
• R20 is selected from the group consisting of benzyl, 3,4-dimethoxybenzyl, o-nitrobenzyl, and triphenylmethyl;
• carbamates of the formula —COOR wheren R is selected from the group consisting of methyl, ethyl, propyl, isopropyl, 2,2,2-trichloroethyl, 1-methyl-1-phenylethyl, isobutyl, t-butyl, t-amyl, vinyl, allyl, phenyl, benzyl, p-nitrobenzyl, o-nitrobenzyl, and 2,4-dichlorobenzyl;
